There are several things you can do:

1- Get a job to cover your expenses until you figure out your long term plan

2- Look for a startup in a similar vertical/category and offer your services. Failure is a great teacher and if you can help another startup avoid the same mistakes you make that can translate into a great service.

3- Do some consulting for other companies. Find companies that need your specific level of expertise and go out there and pitch your services on a consulting basis.

Good luck
