You will need to break out your sales skills and tap the network you just mentioned. On paper, having built stuff for YC startups sounds like you are plugged into an amazing network. So it is a balance of being direct "hey we are taking on new clients!", and a balance of going to events and being more indirect and observant. Go to events, go to trade shows, be social, make yourself known, write blog articles under the name of your group that they can find you under, and if you can manage it publish some open source code. All of this sounds way easier and like less time investment than it really is sadly, but it will build your reputation. But in summary, the consulting gig requires a healthy portion of creative sales skills and other skills, so have fun practicing them all in addition to tech skills. good luck!
