I can vouch for Jay of JGMods. He's a cool guy to work with, gets the job done, and He's reasonable with his prices. I had two items done by his team: painted my rear MTEC bumper, installation, and front lip spoiler -Quality finish.
I don't work for him, but met him at a couple local meets. Maybe you can get a better feel of his business if you can attend some of the local SF Bay Area meets.
