On your second question, what are you looking for? A picker to purchase? A mobile unit to pick for you?
There are some that do contract picking in CO and the upper midwest but for the most part, its to expensive. You are better off buying something or hiring hand pickers.
For processing, how small scale are you talking? We contract pelletize outside of Madison, WI but it takes 30 lbs just to charge the die. There are smaller systems in CO and NY that would only have a 5 lbs waste or so but I don't know of any in CA.
There are a number of growers in the San diego area. You could try down there.
If you are a homegrower, you aren't going to find anyone to pelletize. look on this forum for making hop plugs. Basicaly cramming them into a PVC pipe to compact them into little pucks.
