While I don't know of any shops in your area, you can get a semi-decent feel for one by simply visiting their shop. Talk to some of the employees about what you want to do and see how they respond. If they at least sound like they know what they are talking about, then maybe put them on the short list. I had a shop I was considering and was skeptical until I talked to a guy yesterday. His (apparent) knowledge of the car was enough to sell me on letting them touch my car.
