First, try Craigslist for different quotes. Make sure they are licensed electrical contractors and not just “certified electricians,” which doesn’t mean much. (They shouldn’t even being doing jobs over $500 and must state they are unlicensed in any ad.)
Also, a family member of mine is a very experienced and reasonable electrician/contractor who works in OC and SD. Might want to give Glenn a call at 949 295-2443.He is pretty much availabe 24/7 and has been doing it for close to 40 years.
