Finding one who has done it might not be too hard. Finding one who has done it correctly, might be a bit more of a challenge. Fortunately, there are a few members up there who take good care of their aircraft so may have some good suggestions.
I take my airplane to Stark's Twin Oaks, 7S3. They maintain quite a few Comanches and have a beautiful 250 on their rental line. I think Al Powers (Slimdredger) works with Bandon, S05, I'm sure he'll chime in.
I'm in the middle of my inspection, and one thing I recommend to speed up the process is to purchase all of the bushings and bolts ahead of time. Yes, you can get the go/no-go gauges from Matt Kurke, but I predict the majority will be out of spec. Just buy all the ones you need and turn them over to your mechanic along with the airplane. You should also consider swapping out the conduits while doing the AD.
