Have you been to any shows / seen any of these cats in person yet?
I'm not considering breeding, but just trying to decide which breed I want to own (as a pet) and I still haven't made up my mind...I haven't been to any shows yet either, so hopefully, before I make my final choice, I'll go to a show and get to meet some of the breeds on my "short list" to help me make the final choice.
Keep in mind that if you want to breed, you are pretty much responsible for all of the kittens you produce (i.e. taking them back if their new home shouldn't work out, etc.) so this is a big consideration (and one of the main reasons I'm not considering breeding).
All of the breeds you mentioned are pretty uncommon (except maybe the ragdoll), and I don't think that many people would know what the breed is, just based on name. This will make it harder to sell / place the kittens to the general public that doesn't know what an "x name" cat is... i.e. like in the paper.
If you end up going to some shows and picking a breed that you really love, than you might want to go the long-route and buy an altered cat and show it, build up cred., then get breeding cats and start off...If you have good breeding cats and show them (getting titles and building a solid breeding program) you will develope a great cattery reputation and people will literally contact you to be on a "waiting list" for your next litter. Also, by networking with other breeders (like those you might get your future breeders from) they will be able to reccommend you to prospective owners.
IMO, it would be best to pick the breed you love most and follow the above route, as that will ensure that you end up with quality cats, build a quality breeding program, and end up placing all of your cats.
