Im sorry about the loss of your pet.. however, no reputable breeder.. sells teacups.. because thier is no such thing..Yes, Some yorkies are born smaller than the standard.. up to 7 pounds, but they are just small yorkies not "teacups". The word teacup is actually an advertising ploy for breeders to make more money.
There are some very good breeders here on YT that have puppies, check out the for sale or wanted section.
Good luck with your search..
