Fixing A Dent In A Car

Hey, just wondering if anyone knows about a car repair place to repair dents and scratches in a truck either around the Aree or Nichada Thani (North west out of bangkok) areas? I know in other countries I have lived in, I have found a repair guy who will come to my office to pick up the car and take it to get fixed and the return it back to me - if anyone knows someone who does that in either of those areas, that would be great too.

Thanks!
