I have no doubt that you would eventually sell all of them if you put a cheap enough price on them. But the problem is, they don't always fall into the hands of responsible keepers. Retics require alot of space to properly house them and they are by no means a 'beginner' snake. Plus the food bill isn't cheap. Alot of people buy these snakes not realizing the responsibility they have taken on, or just not bothering to plan ahead. And once their snake reaches 10 or 12 feet in length they can no longer care for it, and the outcome for the snake usually isn't good.
This is just as true for the more expensive retic morphs. Some people have more money then brains. I don't want to discourage you from breeding but perhaps go with a smaller, easier to care for, species that will be more likely to find a good home.
Don't get me wrong I love retics, they are amazing and beautiful snakes. But right now the market is flooded with them and there are alot of retics out there not receiving the care that they deserve. Just my thoughts. Take care everyone,
