i got my yorkie from this breeder; check their website and contact stephanie. they can ship your puppy via ground or air; i think it's best to ship via air; it's less stressfull since it will take less time; it took my puppy 3 days to get to me via ground and she was so stressed.
here is the websire

good luck;
also you can negotiate with them; tell her you are a student and you can only afford certain amount and she will work out something.
the prices include shipping so it's great.
good luck.
