I'd try to get in contact with your local colleges or universities and check with them about entrepreneurship opportunities. When I was looking for a job they were telling me all about it. They have workshops for this stuff where they can help you. That would be my advice. In my opinion, I'd try what you're talking about doing on the side while getting another at say Wal-Mart or somewhere so then if it doesn't work out you can at least keep you're family fed.
