No idea, sorry, you'd have to research your local businesses. Look for mechanics who know what they are doing/talking about. Sometimes you might have to visit and talk to them to get an idea of their workmanship.
Anecdote time: when I first got an Impreza I took it to a local garage who had a good rep, head man pops the bonnet, looks around and says, "so.... where are the spark plugs on this engine?" I thanked him for his time, closed the bonnet, got in my car and left (the sparks in a flat 4 are on the side). Researched a few more and visited the next garage on my list. I was impressed by the yard full of Imprezas (showing owners from far afield trusted them) and the mechanics who clearly knew their stuff, also being owners and racers of these wonderful cars. Years later they are still getting my business.
