Hi and welcome to Yorkie Talk. What exactly are you looking for? Will this be your first yorkie? Are you looking for a pet or a breeding dog? Do you care what size it is because yorkies have a wide range like 3 to 20 lbs.
Not to overwhelm you, but I think it is good to narrow it down and then your search will be easier. Yorkies are an expensive dog to breed so it is hard to find good breeders in that price range but there are some so don't give up. It may just take a while.
You can learn a lot on here on what to look for in a good breeder and how to avoid the bad ones. Everyone on here is friendly and willing to help too.
Good luck!
