You've gotten a good variety of answers and things to ponder in response to your question. Once you've decided on a direction, I suggest you tap into your existing network to see who knows someone you can help. I hope you have kept your network warm over time or this may be a bit of a challenge for you -- but do it anyway.

Don't be "sales-ey" when you approach your network, be prepared to explain to them who your target market is and how you help that market solve their problems. Ask your network for help. And, ask your network how you can help them.

This will do two things for you. It will help you stay in contact with your network (always a good thing!) and it will help you build out your offer so you can make some money to hold you over.
