I'm sure you're aware that there are active Legion and Connie Mack programs in NorCal. Some of these teams seem to play locally only, while some do tournaments as well, and I would guess that the fees vary widely depending on that, among other factors. Some of these teams are quite good, for example, the Hoots. And some not-so-much. You also might try talking to NorCal Baseball. Though they travel and play tournaments, they also play locally, and they can be pretty flexible about how much a player participates in the program.
