Camera Repair?

Hey everyone, I’m a Buena Park resident and would really appreciate some recommendations regarding camera shops. OC or LA county based.

I recently came into possession of around 15 used Canon cameras, mostly 5Ds. They are in varying states of functionality and I don’t have the time or knowledge to repair them myself.

Ideally I’d like to find somewhere I can get them assessed, and get one or two working cameras out of the bunch. It’d be nice to sell or donate the rest. Anyone have recommendations on who/where can help me out with something like this? Thanks in advance!
