Can anyone here recommend a gunsmith in the Miami, Florida area, preferably one who may be retired, and would be willing to smooth out the action on an S&W 357 Highway Patrolman while I watched?

I just watched this video:
S&W Airweight Trigger Job: "The Yoda G Mod" - YouTube
....learned a lot that I didn't know.


I think the video is more so what Terry Gardner is likely to do, when doing a "trigger job", but goes well beyond what a non-gunsmith might be qualified to do, even if he had a copy of Jerry Kuhnhausen's book on S&W revolvers in front of him.

Any advice?
