I've used the house call people on craigslist for both of my last new cars. They usually have a shop, but will come to your home if you're busy and don;t have the time to spend waiting at a shop. I haven't had a bad tint job yet.
Most of the guys are mobile guys. In fact, I'm pretty sure that East Bay Autospa hires out their tinting service. I know ultimate car toys in dublin did it that way. That scheduled me in when they had multiple cars coming in on the same day.
