Jeremy at Wingnut Aviation (907-789-0324) is about the only one that I know of that does much outside work. He's got a guy or two working for him and is real busy. He's always been accommodating in my experience.
There are several air taxis and a couple of very qualified mechanics that do their own stuff but if you're not friends with them they probably won't do any work for you or anyone else for that matter. No offense, by the way, it's just kind of the way it is there.
