There are several reputable breeders in the greater bay area. Any chance you are free the weekend of 5/9-5/10 or 5/16-5/17? There are dog shows going on the 9-10 in Woodand and the 16-17 in Vallejo which would be a great opportunity to meet with and talk to all of the breeders I'd recommend.
I will send you a PM with a list of names and emails as I dont want to post personal emails on a public forum.
Best of luck on your search and kudos to you for going about it the right way!
