I find that as far as selling goes, if you are promoting and presenting yourself appropriately, it doesn't matter how many other ads there are out there. The market around here is flooded with lionheads, many of them priced cheaper than mine, and yet I hardly have an issue selling young stock, most of them at up to twice the price of cheaper rabbits. I also have a lot of people providing word of mouth advertisement - people who have seen the rabbits at market and thought they were sweet and well mannered, and people who have bought rabbits from me in the past, and are pleased with their family members.
I actually anticipate having a harder time selling my Vlops than I do the lionheads. I will be one of 4 breeders I know of in my entire province, the closest one being about 2hrs away, but people won't know about the breed, and they have a different look than the cute and fluffy lionheads.
I don't think that the best way to decide on a breed is to look at the available market in your area. If your first question is "am I going to make money on this", then you're not focusing on the right thing. You should be breeding because you love the breed and want to help promote and advance it, not because you think it will be easy to sell them. I do think, however, that it would be easier for one who shows to sell their rabbits as they will be able to network with other breeders and make sales that way, to other like minded breeders.
I would suggest you go with the Elops, only because you show, and they are a recognized breed. Vlops won't even have their first presentation until 2014, so they are a long way from being recognized, registerable and able to get legs. You're also going to have an easier time promoting them to other breeders, rather than a breed that's so far from getting accepted. The only reason I went with the Vlops myself is the size, I don't care for large rabbits, and Vlops are around 5.5lbs, while Elops are around 10lbs(I believe).
