Welcome to YT, and congratulations on your graduation. I don't have any breeder recommendations, but the Yorkshire Terrier Club of America has some guidelines for breeders that you'd be wise to be aware of. I'm referring mainly to the code of ethics and code of conduct, but there's lots of good information here.

Hopefully, others here will have some recommendations from your area.
