You already have a really good answer, I'll add my perspective.
Thinking that you only have to have those kind of rabbits to command those kind of prices... is a little bit going at it the wrong way around. If you're going to be involved in raising a breed, raise one that you love and are passionate about. Raise one that you just can't wait to go out and feed in the mornings, and are excited about giving warm water to when the weather is nasty and cold and all the water in the rabbitry is frozen; rabbits you love spending time with as you shovel out the barn and clean their cages. Then spend a lot of time learning all the intricate ins and outs of the breed. Learn to assess your baby bunnies so that you can see which are worth working with and which should go to bunny heaven. (The freezer, in case my sense of humor is not apparent here.) As you learn your breed you will learn that all rabbits are NOT equal. Some have poor type, the wrong sort of fur and other flaws. You are never going to get high prices for those rabbits... and even if you do manage to fool someone in to paying a high price for that, all that will happen is people will learn they should not trust you.
People who get high prices like that usually have worked really hard to get there. They've spent years breeding the best to the best, culling, working through frustrations and trying again to get the best rabbits. Then they work hard to promote their rabbits, putting up a website, going to shows sometimes far from home, putting advertisements in magazines... and none of that is free or easy.
Just like with showing chickens, showing rabbits takes a lot of work and dedication on your part. Are you willing to do all that hard work? Can you put in all those hours of study, of visiting other breeders of your chosen rabbit breed to learn what you can from them, to travel to the shows and put your best bunnies on the table?
That's what it takes to get good prices for rabbits. Or chickens for that matter. It isn't just a matter of picking the most expensive breed and then the cash starts to flow in... doesn't work like that, sorry.
