There's an organization of retired executives (SCORE) that helps people start their own businesses. I had thought that I might try to take photography full time since I was so unhappy teaching in my present school, but I just found out (a few weeks ago) that I'll be transferring to another school, so my efforts will be focused there. SCORE was a place I was going to go to get some help doing that.
I don't have any experience in starting up a company, but that was a direction I was going to head. Hopefully that at least gives you a direction.
