Is there a shop around Gwinnett area where I can go to do something simple like installing HIDs and stuff like that?

I went over to Ball and they say they only do engines. So I went to the shop beside Ball called OTS to see if they can do my Xenondepot lights. The guy said he been doing cars for around 16 years. I ended up with one of my driver side not turning on at all and my passenger side light going off on my way back home, and $100 poorer. That guy just said that my kit is sh!tty (I've never heard or read about any complaints against Xenondepot).

Anyways, I dun wana mess up my lights any more than he did so I wana find someone more professional and trustworthy to help me see if he did a bad connection and try to fix what he had done. Anyone living around Atlanta or Gwinnett county please help by recommending some shops I can go to. Thanks!!!
