I really don't know how to find someone, I wrote the emails myself. What I know is how to talk to people to close the sale - and most of it is just about making people feel secure, and going above what they expect.
Aggressive pushing almost never works for me. Just be nice, see if your product really solves their problem, point out what they will save in time and money, and make sure you are there for them.
To do these type of selling you need someone smart and who has empathy with people. Then just monitor the emails they send to make sure they don't sound marketey or selling too hard. Also, they should not get a customer too excited before purchase, cos the customer finds it hard to back down then, so usually just disappears. The customer wants to feel like he chose you, not like you forced him to buy by being so friendly.
I'm in the same boat as OP as to B2Bness-of-product and experiencing cold-email-fright at the moment.
The process is like this:
1. Approach your customer with a solution to a problem he has. Focus in the start ONLY to get him to reply your email. Don't sell yet! Make sure he replies, and half your task is done
2. When he replies, be honest about what your product can do for him, and if he needs it.
3. Allow him test it, or give him some special access, making sure to back off completely at this point. If he feels under pressure, he'll disappear. He has to impale himself on your stake, you don't drive it into him
4. After that, if he indicates interest to buy, make it easy and painless for him
It's really all about honesty and solving peoples problem, the rest is just about not fucking up. It's like meeting a girl who likes you (customer that needs your product).
It's all about you just not fucking up the process, that's it. Just guide the person to the sales page gently, without being overeager or annoying. If he does not want it, he does not, if he wants it, he'll buy it you don't need to really sell it.
A personalised email for EACH site individually. Hire someone to do this if neccessary. Track your replies. If nobody replies, then you don't have a product. Otherwise, lead them through it.
The more emails you exchange with a customer, the more likely he is to buy! B2B is all about communicating with the customer, making him feel safe with you, like you are a partner taking care of a small part of his business.
Always end every email with a hook that will make him reply to you.
Press-Release, Relevant Blogs and so on are NOT going to make you customers. You have to reach out personally! Your market is too small, too in-cohesive and too static for anything other than aggressive personal approaching your customers to work.
I've done years of these types of sales, and I hate it with a passion. If you don't like writing emails to people then figure out how to get someone else to do it for you.
