A San Diego-based guy is Phil Barrick with OneTouch Home Theater (619)838-8333. He’s been doing the cabling for Shadow Mountain Community Church for over a decade. Phil@onetouchhometheater.com is his email address, but calling or texting is usually better. He has done work for us at a small site we have up in LA, so I’m guessing he might be able to help you out.
