There is a company at this Web site that describes its business as chiefly installation of electronic equipment purchased via retailers but requiring professional installation. Minimal Yelp and no Angie's List for the San Diego operation...and Web-based service request feature didn't work for me. I've now sent them an e-mail at (edited) e-mail address I found at
http://sandiego.zipinstallation.com/, purportedly one of about 20 partnership "branches" around the country. We'll see what happens. My attempts to use Service Magic and other search engines have not been productive.
