I wish I could answer, but confidentiality agreements make putting out a list on the internet a bad idea for my career. I'll just say that I work in Los Angeles at a very high end AV and Automation integrator with a lot of clients in Brentwood, Palisades, Beverly Hills, Bel Air, Mullholand, Hollywood Hills, Malibu and the Beach Cities. I've met a lot of them in their homes, and some were super nice and cool, and some just don't make eye contact. If you just pretend you have no idea who they are they usually are much more relaxed.
The people who really blow me away are the agents, and producers. Also if you see the way the super rich family money people live, the celebrities can look like chumps by comparison.
