I know of a bunch of places in the San Jose, Ca area but it looks like your in Riverside. If you're looking for mail order try Bass Pro Shops as they have/carry the entire Gammie product line including the hard to find sizes.

2/0 and 3/0 EWG hooks are pretty common at just about every fishing store up here in the San Jose area. I would assume that a local shop would carry them as well. Also try Bass World West as they are probably close to you. I believe they do mail order as well.
