Getting the first bees

I would suggest joining a local club. That way you’ll hopefully have good experienced people close by with local knowledge. Often through local clubs you may find people who are wanting to split hives or hear of swarms and possibly come help or show you how to catch a swarm. There are a few people from California on this forum who may be able to recommend some clubs.
