I hope your little one recovers, and know I would be a worried sick. Here is a link that was posted recently that might help you.

These little ones cost a lot, and sometimes getting a good deal from a bad breeder costs more in the long run. Glad you were able to take her to the vet, and I really hope she she isn't suffering.
