Hey just wanted to chime in, don't let people tell you that you can't make a living doing anything reptile related. So many times I see breeders who sell $20,000 snakes give the old "it's a hobby that pays for itself, I barely break even". I don't know if it's to discourage you from becoming competition, an attempt to limit the amount of people who get involved with breeding because the market is extremely flooded or any other reason. If you have passion for something and enjoy what you do, you'll find a way to make it happen.
There are a lot of high end geckos out there and many colubrids that produce large clutches with high end morphs. You can do it.
