If you are trying to stay local, how about checking with your local vets? They know if they have clients that are breeders. Also, if you encounter a breeder that doesn't have any puppies available at this time, ask if he/she can refer you to other breeders, so you can expand your search that way.
I too am looking for a (2nd) pup. I'm willing to drive across state or out of state though if necessary to find what I want. Yorkies have a long life expectancy, so I'm will to travel to find what I want in my life for the long haul.
Good luck in your search
