Camera Repair

Howdy. I am looking for a camera repair shop for my Yashica FX-D Quartz. I am not exactelly sure what is wrong with it, but the trigger release button does not work. I think it is an electronic relay issue.

I am wanting to know if there are any good shops in the Dallas/Fort Worth area that would be able to fix it. It's a really cool looking camera that was my grandfather's and I want it to be in working condition again. I really want this manual to be working again so I can control the setting better than my Yashica FR-II.

Also, would a Sigma lens be good for a 1:1 Macro?

Should have mentioned this. I am also willing to send it somewhere to get it repaired. I just really really want a good repair shop that y'all trust to fix my camera.
