Well it sounds like you got a plan there, and even a way to make some money. Honestly that does make me relieved to hear, I have heard from far too many kids getting chinchillas only to have issues of their parents refusing to pay for things, and since they are under legal working age they have no way to earn money themselves. I think you will be much more set then you get your chin then a lot of new chinchilla owners, even a lot of adult owners.
