IDK what kind of, or how many responses you might get here. I would suggest, if you haven't already, attend some dogs shows and try to meet breeders there. I would think breeders would be more likely to want to mentor you if they could meet you in person.
I noticed there is a silky terrier show (not yorkies, but still would be interesting) in your area real soon. Then a Columbia, MO all breed show later in March.
