I am so sorry to hear of the loss of you Yorkie. It seems Yorkies are everywhere these days, but not always available through reportable breeders who care about providing healthy well adjusted and socialized dogs/pets to families.
As for your search for a reportable breeder and not a PM this is what I found on the AKC website.:
Yorkshire Terrier Puppies for Sale - AKC Breeders - Puppy Tips
I hope this helps you in your search for the perfect addition to your family!
