I would really suggest that you take a "trip" and visit with breeders or barring that plan on a trip once you make contact with a responsible breeder to fly in to pick up your puppy. Many times they are not close and there will be some travel involved. I would suggest you contact the breeders directly and see what suggestions they might have for you. I know that when I got my last two girls, I flew from SF to Chicago, drove from there to Cleveland, Ohio for one and then back to Chicago for the other (and a boy puppy too) and we all flew back to SF with the pups in a Sherpa. Do take care that with breeders that advertise "will ship" that they are not always responsible breeders…. In my case I will not ship a puppy alone as baggage, all potential buyers must come and pick up their puppy from my home.
Keep in mind also that a responsible breeder will usually pick the puppy that would in their opinion fit best with you and your life style. It is very unusal for a responsible breeder to let someone just come and choose a puppy.
