Yup, we have Dentmaster now here in the UAE, also, one or two shops here now specialise in rim repairs etc, not sure what the cost is mind you.
I did hear that Dentmaster charge something like Dhs400 or 600 per panel, irrespective of the number of dents. Also, rim repairs are something like Dhs150 per rim, but i could be way out on that.
thankfully, not had the pleasure of having to ring them.
