Stebo, I've used Dent Wizard a couple of times with good success.
They use what is referred to as the "paintless dent repair" method that can save you money and retain the integrity of your original finish. A lot of car dealers use them, and their competitors, to quickly and inexpensively fix dents.
If your dents don't include broken paint, sharp creases, etc., then they usually have quite good success at removing the dent without any trace of it having been there.
You must realize that like most things it's more a factor of the actual individual doing the work then the company they work for, so I'd suggest if you go that way to find out who does that type of work in your area and if there's more than one in the general vacinity try to check their comparitive reputations and choose the one with the best reputation.
Regards, Alan
