I think you should look for a new shop. I can always get my car in the day I call. I don't think it has ever taken more than 3 days to get it back. And that was when I needed a new rad and some bodywork after an animal collision. The amount you might save by taking it to him is more than offset by the aggravation of not having your car. You are still paying insurance for this downtime too. 2 or 3 weeks to just look at it is inexcusable. Plain and simple.
