I have been working to get an account at a distributor in the Los Angeles area. I can get it all delivered to my office in West Los Angeles for orders of $250 or more (+ a small fuel charge). I have prices for Caputo 00 (both 25KG and 10/1KG) as well as San Marzano DOP and some other ingredients.
I found that Restaurant Depot and even Costco (where I also have accounts) have better prices on mozzarella, so I'm mostly focused on the flour and San Marzanos.
If anyone in the West LA area is interested in placing a group order, I will arrange, charge you my prices and you can pick up (cash) at my office in West LA.
Alternatively (and admittedly selflishly) I'm happy to place a smaller order (which we can share if you don't want 25KG of flour or 12 cans of San Marzanos) if you are interested and willing to pick up in City of Industry and deliver.
BTW, as of now, the Restaurant Depot on Jefferson has no pizza flour and Surfas, as expected, is highway robbery--$11 for 3 lbs of Caputo 00.
