First off, welcome to YT!
We do not allow threads begging for free puppies or looking for puppies at extreme reduced costs. Yorkies are generally from $500 on up, with most being in the $1000 to $1500 range. Please do not post looking for Yorkies below $500. If your budget for a Yorkie does not allow for $500 or more, you may want to look into Yorkie rescues or adoptions of older Yorkies, as they may be better suited to your price range.
^^^ That's from the rules section. Sums it up nicely. You are going to be very hard pressed to get a pup from any ETHICAL breeder for such a little amount. Given the amount of costs breeders have to cover, it's really not hard to understand why.
Be patient, I'm sure you'll find the perfect little one soon.
