I have no advice, just a anecdata: Me and people I know got into consulting, because we were interested in certain technologies; really interested, researched all stuff, tried to answer all questions on those matters, engage with people online, organizing events. And all of the sudden, people come to you with business cases, questions and consulting gigs. I see consulting for money an extension of something, that you are already passionate about (I mean professionally passionate, you don't have to pour your identity into it). The idea is not that hard, it's just that you have to have enough energy and sitzfleisch to see these things through.
