Work part time to pay the bills and spend the rest of your time working on your projects. The $60,000 of yours will disappear faster than you think. You'll eventually spend money on the business I assume.
If you post your email / contact info on your profile, I can reach out with some ideas. I work in NYC and happy to connect you with people depending on your interest areas / skillset.
Either through your network or do some freelancing. If you go the freelancing route you'll have the extra benefit of having a relatively straightforward way of developing other business skills you'll need like sales. Just be sure not to let it take up all your time if you're going for a different business model :)
