Go to the AKC website and look for a conformation or specialty club in your region. PA, NY and NJ all have clubs that can help you find a good breeder. The clubs all have a breeder referral person who will help direct you to people they know who breed what you are looking for.
These people travel around to shows and know a lot of people. Here is a link to the search page.
