Everything I've learned from playing the Grand Theft Auto series of games, tells me that a city like yours should have no small number of fly-by-night body shops..
Think it depends on where the dent(s) is. I've seen guys use a regular plunger to pull a cave in on a door or light sheetmetal fender area. I just had (well, the dealer had) 3 small dents on top of door body line (just under mirror) and that metal appears to be pretty thick. It took the pro almost an hour to get them out.
