  BYB from FAQ sticky: 
"Breeders fit into categories and like any business there are levels of desirability. There are the high profile professionals, those who exhibit and advertise regularly being dedicated fanciers, and then there are the “Mom and Pop” breeders who have litters just a few times also known as “back yard breeders (BYBs)”. " 
I'm not sure there are enough professional breeders to meet the demand for Yorkies.  
There are also pet stores, brokers, & puppy mills below the above pecking order.
