These places do exist, I worked on friend's car at an awesome place called Lifted in Fremont. They had all the tools you could want and a knowledge crew to get you out of sticky situations. It looks like there are a few other places throughout the Bay Area too. I think the challenge was inexperienced people coming in and underestimating the task they were taking on or screwing things up and having to leave their cars at the shop for what was originally a day job.
