Whew, I don't even know what to contribute here. Car care is akin to health care challenges. It is extremely difficult to find a competent, trustful mechanic. Word-of-mouth is maybe the best way? I almost can not believe that any mechanic does what we DIYers do regarding cleaning everything up prior to reassembly.
Kudos for educating yourself and self advocating about brake work. Many/most of us here probably forget what it is was like when we just "drove cars" and didn't have knowledge about the mechanical workings. Keep up the learning so you can communicate with the mechanics and avoid being taken advantage of. I'm not sure that a brakes-only shop is any better than Firestone, etc.. Good luck finding a good shop - sorry I can't help more (as you found out, YouTube is priceless).
