That where I got my furbabys at, try there.
She is in TX (where I am from). The lady is really nice and will work with you. As long as you have the pup payed off before you pick her/him up or shipped, then she has not problem with you paying how you want. She has a little due soon.
Best of luck and welcome to YT
