A lot of breeders I contacted out of state charge $300 and use Continental. They can't guarantee the condition of your puppy or even that it will arrive alive because they are sent cargo and it is highly subject to weather conditions!
I had mine shipped from Ohio to California and she flew with somebody in cabin for $275. I think that the young woman's mom was a stewardess' daughter and used her family fare rate to earn some extra cash. My puppy arrive safe and happy.
