In the thread on consulting a few days ago a great point came up: if you can translate your skills into value to a business, you might end up having conversations with people they didn't know they wanted to have. An example: you can go to a tech meetup and pitch yourself as a full-stack Rails developer, and try to get work from people who know they need Rails developers -- or you can go to a finance meetup and pitch yourself as a solutions builder, and end up getting 10x the revenue from a project that's turning a spreadsheet pipeline into a CRUD app.
My take on networking, and what's been working for me, is to reach out through people you already know. They might not be hiring your skillset, but they might need a solution to a problem. Almost all of the work I've been doing lately has come through intros, and several of those started off as fairly cold relationships. For example, I applied to a startup incubator, whose founder decided I was smart but too early in my idea, so hooked me up with another founder who needed some heavy lifting done on the Android side. Other projects have come through more direct referrals, but almost all have been for startups who are flexible on parameters (including time, remote, etc) and who don't even have websites, let alone job ads.
Definitely they are hit and miss; but I have found that to be true in all forms of networking. This should certainly not be your only avenue for networking.
I take multiple approaches to networking. Meetups, events, conferences, calling/emailing people I already know, cold emailing companies directly if I know they use a technology I specialize in. I also wear T-shirts almost constantly that are simple and state the nature of my business and a phone number to reach me at.
Does the T-shirt approach work? I've wondered what would happen if I put my details on my laptop skin, as I work from a lot of SF/Valley coffee shops :)
I have bought large numbers of T-shirts and give them away as well as wearing them myself. I honestly don't have any statistical evidence that shows they have worked to gain me more business. However I always wear these when going somewhere that I specifically intend to network. In the same way as having business cards does; company branded T-shirts lend credibility to your business and I have been approached and directly asked questions about my business from wearing the shirts.
And believe me; I totally understand the uncomfortable at introducing yourself point. I am an introvert by nature. I have a rule for myself when I go to these places; I force myself to do a minimum of 2 new introductions each time. More is better, but a minimum of 2.
To me, this sound like: if you accept a fixed rate contract knowing it'll work out to $10/hour, you can be employed for an entire year. Yes, please.
$75/hour is my standard rate and this is anything that lasts 2 to 5 months and is either new project/features, or a generally decent code base (most clients are happy to allow me to look at the code before we agree to rates and moving forward; some may want a non-disclosure signed at this stage though)
If the work is guaranteed for a 6 months + contract then I will bid my normal rate of $75/hour to start, but will then negotiate with the client and give them a better rate, but then there is a signed contract clause that explicitly states there is a time based discount contingency; in they event they cut it short then it they essentially owe the difference between the normal rate and the discounted rate.
Putting that into perspective; if a fixed rate contract comes out to $10/hour then I'm making in a day what I would typically make for 1 hours worth of work.
I decided to begin contracting in 2011; the work was sporadic at first, but for the last year and 1/2 it has been growing steadily. Last year I left hours on the table (e.g. existing clients wanted more of my time than I could fulfill; and this was with bringing aboard 2 sub-contractors). I spent 3 years of hard work networking and selling myself, but the last 3 contracts I had were acquired by people in that networking calling me and asking if I was available. From 2012 to 2013 I saw a 3000% increase in revenues. I expect to grow revenues again this year contingent on finding good subcontractors, but not nearly as much so as from 2012 to 2013. I would anticipate somewhere between a 300% to 400% growth rate is more realistic this year.
I often try to keep a little retainer left over at the end. Some say I should keep this for "change" orders. However, I will give it back to the client! Why? 9 out of 10 times when I offer to return the leftover they are ready to add it to a new retainer for another project. You can't make a client happier than saying "here's the final demo of your project! It was great right? Oh by the way we came in under budget." Just make sure you are in constant communication with the client, have regular demos, and deliver something amazing.
People talk about people; within your network you quickly learn who is reliable, who is honest, who isn't, etc...
Also when I bid work for a client; while I bid hourly I am open about the reasons. I tell them point blank how many hours I believe their requirements will take to implement in a worst case scenario given they do not change the requirements. I then tell them that likely it will take less hours than that, but they need to know how much the total cost could potentially be. If the customer is still insistent on a fixed rate contract I explain that it can be difficult to prevent scope creep for customers when there is no dollar amount tied to it; and that I want everyone to be happy. I explain that if they really want a fixed bid I can make an exception, but that the fixed rate pricing will be double to triple what we have agreed upon as the max cost associated with the project. I explain this is to cover the scope creep that will inevitably be introduced and to protect myself from the loss risks associated with such a decision. Most clients then agree to the hourly rate; the rest keep looking for someone else.
Depending on where you are targeting geographically those technologies vary a lot; I personally have seen a lot of demand for iOS/Android, but even more demand for Ruby on Rails. I think that quite a few Ruby on Rails developers left the community and flocked to Node.js as the next shiny thing and that has just made it easier to find Rails contract work.
Not only is it easier to find work in a less mainstream technology, but you are able to negotiate better rates since it is more difficult for businesses to locate help. After a certain point you can't scale by taking on additional hours; so your hourly rate makes a big difference.
And hourly vs fixed rate contracting should be considered. I will negotiate my hourly rate based on term of contract, but under no circumstances will I take fixed rate contracts any longer. Quite a few of my friends in the contracting scene are the same way. I've seen too many times where this just leads to continual "feature creep" and a strong difference in opinions of if scope of work has been expanded beyond the agreed contract (in all cases it was). I bid a fixed rate contract with a couple of associates against my better judgement. Based on the initial scope of work it should have taken about 3 months. Instead it took over a year and the lead developer on the project walked away making a rate of right around $10/hour.
And this point can not be overstated.
Network! Network! Network!
If you are an introvert you are going to have to get over it. It doesn't matter if you have the raw programming skills of Linus Torvalds or John Carmack; if you can't get out there and make connections you aren't going to make any money.
I am very introverted by nature, but I force myself to regularly attend meetups and conferences; and make a point to connect with new people at those conferences. You need to grow your real social graph; not your Facebook/LinkedIn/etc... Nothing makes the same lasting impression as a firm handshake and 5 minutes of conversation face to face.
