I consult, I teach (distributed systems) at a university, I sit on a few technical advisory boards for a few companies. I don't really go out of my way to find clients; word gets around and I get referrals. If the problem interests me, I'm happy to sit with the potential client and give pointers and advice (for no charge) even if I don't want to take that project (cf. rule 1 -- never pack my calendar). It is a win-win.
I've also gone and worked for a postdoc salary (at Berkeley, on the Bloom language) because the project was so interesting. Once you own a home outright, and health insurance is taken care of, the other expenses are completely manageable. I don't need to earn a lot to lead a rich life.
