There's a place called Antone's in Newark next to Fremont. The guy has been around forever. He lives and breathes guitars. I took my bass to him a couple of years ago and he did a great job setting it up for me.
He knows his shit!!
Have you tried the little shop behind Gelb Music in Redwood City, I think is called the Amp Lab (yes, they also do guitars). Or the guys at Gelb may be able to recommend a place, they're very helpful.
