Oh that's easy, wait the 3 months and then quit. Subcontract out among your friends to make up for the immediate work you can't take right now.

Spend an afternoon to setup some branding for you data/ml company and when dealing with customers, mention you're a company and that they're not just hiring one guy but that one of the team will handle it.

I'm in a similar position. I'm saving money to build my house, I don't want to quit my main gig just yet and I'm trying to ramp up an agency doing mostly web development and I had good results offloading part of the work to other people. Learning to rely on external resources is crucial if you want to scale your business.

Best of luck!
