Well here's the deal
The reason nobody really wants to touch it is that yu won't really like the numbers they give you for cost. A body shop can make more money on bodywork than they can doing time consuming custom stuff.
As to the sandpaper comment. Sand it yourself and save a good chunk of money. Spraying is not that much time but be warned paint ain't cheap. I just a pint of color matched urethane for my truck.
My jobber rate was $34.00 for the pint of just basecoat paint. Plus reducer, plus clear, you get the idea now?
I know driving is kinda out of the question. There is always UPS.
As far as it being us guys. I don't do this for a living. I just learn how to do things as I go. I still learn. Have friends that teach me things I don't know and vice versa.
