I agree with Chachi. Sounds like you'll have to pay the breeder the fee she wants. Coming up with the fee shouldn't be too hard as you are selling the puppies. Honestly, if your potential buyers only knew a CKC registry is not good (the preferred registry of mills, and byb's), they probably could care less about the papers.
I feel bad for this yorkie, 4th owner, and used only as a breeder
