I would have to say no on all. I used to work as a bodyman/painter & and am now in auto claims appraising, so I know my way around the body aspect of repairs.
I would think if you produce a good quality product there would be a good response from quite a few people who are wanting to learn what you know & should do OK with it. A lot of do it yourself restoration guys & gals would be well off to have a good quality educational video to assist in their projects. Good luck with the endeavor.

The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
