I see.
I guess what I don't understand are you reasons for wanting to breed. With any and all animals that I've bred, I never once bought the first animal of that species with the intention of breeding. What I did was buy an animals that I liked (a corn snake, for example) to have it as a pet. After getting to know more and more about said species, and how to get them to breed in captivity, I decided that breeding was something that I'd like to do to further my knowledge, experience and involvement in the animals.
What concerns me is that you aren't looking to breed an animal that you love and want to work more with, but are instead trying to breed an animal that will make you money. Doing this can taint your view of your animals as potnetial dollar signs and not living creatures, which is exactly why commercial egg producing hens and beef stock live such horrible lives. I'm not saying that you would do anything close to that, just that dollar signs are what causes those conditions.
If your parents won't let you breed unless you'll make money then just continue to keep reptiles as pets until you are out of the house. Then, if you want to breed, get whatever your heart desires. Best of luck.
