i dont breed leos yet but i know a lot about business (but yes i am 13). Keeping the leo space savy isn't going to do well unless you use racks. You might be able to make multilevel cages but they will cost a lot more money than racks. Also if the business is going to succeed you better have good geckos, awesome marketing, and lots of willing buyers. Lots of full time leo breeders barely break even. If you want to breed any herps for a business and you dont have a website you will lose lots of money. also who are you selling to? a pet store isn't going to buy a SHT/SHCT/SHTCT or any other morph that is over $50 because they wouldn't have anyone buying. Neither is a 10-12 year old kid who wants a pet lizard. Remember just because people are willing to buy a gecko for $500 doesn't mean a little kid is going to pay more than $50 on it. I helps to have variety so you can sell to a multitude of buyers (kids, petstores, breeders,herpers, etc).
