Alot of vendors sell CVV by ZIP, buy 100 or however many you wish, the more the better.
search for those BINS in Dumps vendors lists, they should be good for your area. It's still a process of trial and error for finding the best, this can just narrow it down for you.
Even if you dont use the CVV, at 1 dollar or so a piece, the investment for your dump-work is well worth it.
