There are very few breeders on the West Coast. Your closest will be Cheeks and Squeaks in SoCal (cheeksandsqueakshamsters.com) or Nantucket Hamstery in Illinois (

I know neither are "close" options. Sadly, the USA is so fragmented, we don't have breeders in most states... we're trying to change that.
