We have a lot of similarities, I wish you luck. Maybe you can be the inspiration for others depending on what you find.
Have you ever thought about vinyl graphics, wrapping and decals? I wouldn't suggest to just anyone to start their own business but it starts with quite low overhead costs. If you're wanting to actually work on cars though that will not get you far. It might however help with your interests in design.
Again, good luck and I hope you find something. We all are looking!
Well except Tcoat I think he only looks at these forums and his car.
