Wanted to express my sympathies on your loss and wish you luck in your search. I just wanted to let you know also that most reputable breeders keep their Yorkies until 12 weeks and certainly wouldn't let them leave before 10 weeks. It's much better for the pups socialization as well.
I'm not sure about prices where you are but here are a list of breeders that belong to the YTCA

You also might want to try a rescue although I'm not sure how many young puppies they would have. I wish you luck!
