Used barrels in SoCal?

I get rather frequent requests for a local source of used barrels, mostly because the shop I work in has two of them fitted with round glass tops for table service. I’ve been telling people to call the few wineries close by, and also those in Temecula. These puppies are heavy, so shipping doesn’t seem like the best idea. Is there a place, near South Orange County, CA, where used barrels go to die before being cut in half for plant nurseries and garden retailers?
