Please don't take their unwillingness to sign over breeding rights as an insult. You have to understand how much breeders put into making their lines what they are. The worst fear of a breeder is that their pup end up in an unloving home, particularly the hands of someone who wants to just mill out pups and get $$$. Sure YOU may have the breed's best interest at heart, but THEY don't know that.
I would advise that you search and find a breeder that is willing to mentor you. You would be surprised at how willing some would be...it can be a win win situation. They get help and you get knowledge.
Once you show that you are serious and that your intentions are good, you'll be shocked at the support and help you'll recieve from established breeders. You'll also be surprised at how much more you'll know as a breeder yourself from the experience. Perhaps a vet could help point you in the right direction?
But don't wait until you've worked out an arangement with someone, start now...read up everything you can get your hands on.
Good luck!
