I guess it wouldn't hurt. Just what scale are you talking about here? A small scale or larger? Yes, there are lots of breeders, but they are all different... Different morphs, different goals, different specimens and different results of course. It's not a huge venture... times can get difficult if you don't sell since you'll have lots of mouths to feed. I breed on a very small scale, mostly to hold back my own but just started a site to maybe expand sales out of the local area. (Though I do prefer local sales)
It also depends on the cost you're willing to cover for a business. If you are to treat it as a regular business, lots of money will go into it prior to making any money back as well. There's the racks, supplies, the geckos, etc...
I suggest as well if you were to go into it as a full on business rather than just a hobby, you look at it from a business perspective as well. You'll have to find out what sells, and what doesn't. Those are what you want to purchase as your breeders. I personally breed what I like (not what sells), since my purpose isn't fully business motivated. I like to be able to keep my offspring for myself and my children. We have several tanks in the house that are pets only... And some that are breeding tanks. If you were to really want to breed for business, then you'd most likely need to research the best selling morphs and purchase them rather than just breeding what you've already got. Everyone has a certain preference so it doesn't mean what you like is what will sell. I breed Enigmas, Mack Snows, and Raptors because I like them, not because they sell. If they do they do, if they don't, well... more tanks in the house for me.
Also, if you're talking about a large scale breeder, then unless you want to lease a building for the business, then you'd definitely have to turn an entire room in your house as your breeding room. You'll definitely need lots of racks that would most likely take up an entire room. I'd also suggest breeding their food yourself since that many mouths to feed can get expensive. People that do it this way either have lots of $$ to start with, or takes years to expand to if you do it the cheap way... (which is start out small, then grow as you sell more)
Just what scale are you talking about?
