Get a breed of rabbit that can be both. I have silver fox rabbits. Beautiful rabbit to look at, endangered as well and a good eating rabbit.
Maybe not quite as awesome as it sounds. For one thing, Dutchgirl is overlooking the fact that a doe eats about 3-4 times as much feed when nursing as she does when she isn't, and a litter of kits eat like little pigs from the age of approximately 2 weeks until they are old enough to sell (approximately 8 weeks of age). I would estimate that those 6 litters per year would at least double, probably triple her feed costs. Most does lose their first litters, and their litter sizes tend to decrease after the doe reaches 2 or so years of age - so 7 babies per litter gets a bit optimistic (many breeds and does never have that many babies even at their peak of fertility). For the kits to make good pets, they need to be handled a lot, so a good bit of time needs to be invested in them (of course, playing with baby rabbits is such a chore, right?!) Finding buyers for a handful of kits may not be that hard, but finding homes for almost 50 kits per year may be a different issue - some sort of advertising may be needed, and that may be yet another cost to be factored in. If you sell more than $500 dollars' worth of small animals to a pet shop in a year, you need to have a license. If you have really top-class rabbits and want to do the showing thing, there is the time and expense of entering the show, the gas required to get you and your rabbits there, etc.
