I used these guys in south Dallas. Not on the same level as Advanced but they only charged me $250 for each of the bumpers on my 69 Firebird and they both needed straightening. I would recommend that you blast the backs of the bumpers if they are rusty since they didn't do it on mine. They turned them around in a week.
If you are considering them I recommend you get them to do a test bumper to make sure you are happy with their quality since my build is nowhere near show quality.
