Actually, I would appreciate some advice on this. I truly don't know what services to sell. I can set up machines, design databases, write graph algorithms, train machine learning models, design web services, etc. But I'm not a "leading expert" on any of those things. I'm a generalist and usually have an answer for any problem I run into simply because I've run into it before. How do I market myself as a general problem solver?

I'm in the exact same boat and would love to hear some ideas.

There should be a market for people like us. My personal network is not large enough to build a practice around. Have you had any ideas on this?
