There are a lot of companies that do this, I have a mobile guy that will come to my house if need be. Some of the other companies are called Dent Wizards, Dent Doctor......look in the phone book. The other way is to go to any high end dealership and ask them who they use. Most of these guys are mobile, my guy has a network of dealerships he covers. The dent can not be on a crease and if the paint is broken then it needs body work, they can't fix those. I had 26 hail dents on my black PT and they fixed every one, you didn't even know they were there and it took them one morning not days in a body shop. PM me if you are having trouble locating someone.
