Hello,
Good luck with your search. We're in Mohnton PA (just outside of Reading) but we are more expensive than what you're looking to spend.
Heck, even the pet stores around here sell so called Yorkies for $1200-1800+
I say "so called" because they don't have papers, they are most definitely from a puppy mill and you can tell they are a poor example of the breed. But many people don't know better.
