You might want to start by going to some local dog shows, and trying to talk to the yorkie people there. Also look into local breed clubs and talk to them (they are usually the same people who show dogs). You can then learn more about yorkies, and get a feel for the breeders you might want to work with.
If they don't have a puppy right away, you will usually get on a waiting list.
Please see my yorkie website, I have tons of good info there.

Please see the left side menu bar for the specific yorkie information.
