I presume you mean a pedigree?
As lankeela says, you need to find some stud cats. Another good place to try is your local cat club; they will be aware of all the local studs. If you get stuck, you can search on the web for studs (yes, really) or ask the GCCF for contacts.
You'll have to be careful when buying to be sure you get your cat registered as 'active' otherwise the offspring cannot be registered as pedigrees. Some breeders will not let 'non-professionals' have 'active' cats. If you aren't bothered about having documented pedigree kittens, then it doesn't matter.
Also, you'll have to be sure your new kitten has all it's jabs, including FeLV, as stud owners are very fussy about who they let go with their studs, on medical grounds.
BTW, don't imagine for a moment you'll make any money out of this. It will cost you money, really, to have the kittens.
