If you are breeding for meat, there are of course the reliable standbys of the Californian and New Zealand. If you get good animals as breeders, they both have a good, meaty carcase and a dense pelt. There is a slight problem with breeding for meat and fur; namely, rabbits are usually slaughtered at somewhere between 8 and 12 weeks of age, and the pelts are junk at that age. Oh, they may be pretty, but it's baby hair, it's molting - the truly prime coat doesn't come in until later, and the meat of the older rabbit is tougher. If you intend to use the pelts yourself, the lack of density may not be a problem, but fur production is a pretty special niche market. If you are looking to sell what you produce, meat and pelts kind of cancel each other out.
If you have good, healthy, productive breeders, selling their offspring as potential breeders (or for people to slaughter themselves, some will do that) shouldn't be difficult. However, if you are thinking of selling as pets, the pet market generally prefers animals that will remain small. And while you certainly can eat smaller rabbits, it takes longer for them to get big enough to make slaughtering them worthwhile, and of course the meat is tougher because the animals are older.
