Hi Andrew and welcome to the board. . .
To be honest with you, it will be far easier for you to go to the groups. I know it's a pain but that's how life is at times. Nonetheless, you could go to the
IBM web site and do a search for rings in your area (just shoot them an eMail if you can't find a search engine or listing); I'm betting however that you'll have to do some driving.
Look up magicians in the phone directory, who live in the region, Chuck Magnosa is a good start and I believe there's still a magic shop in San Jose that could give you some help if not, well there's that added 45(ish) minute ride north and west (from San Jose) -- the Bay Area is more than ripe when it comes to magicians and magic resources. I'd start with the guys at
Misdirections if you end up heading that far.
Best of luck!
