First off, welcome to YT! I am very sorry to hear about the passing of your little one.
Secondly, as others have pointed out, there are no reputable breeders of "teacup" Yorkies. Ethical breeders strive for healthy dogs that adhere to the breed standard--they do not purposely breed to achieve extremely tiny dogs. So you will be hard pressed to find someone recommending a reputable breeder purposely breeding tinies. If you want a smaller dog, then I would suggest that you talk with some breeders and ask to be put on a waiting list in case they have a smaller dog born. It does happen, just not purposely.
