Not that I know of, I am the only one I know of that has got a history as a car dealer, which sadly for me makes me sympathetic of the problems you guys have.
What I think is a good idea is when your current dentman says no, then ask another one if the only other alternative is a bodyshop, I know of many guys who if the dent will take longer than 10 minutes are not interested in it, why should they be as we have plenty out there to go at. Myself I enjoy the challenge and do not need to earn as much as some of the other guys and I certainly do not want all the rushing around any more. Being semi retired is fun, I hope you all get to try it.
