Here's a link to CA appraisers associated with the Int'l Assoc of Auto Appraisers, the organization I've been with since '96. I've had good experiences with most members, but you should do your due dilligence and interview anyone you're looking at hiring. Everybody has their strengths and weaknesses. Good luck.
