If there aren't would you please copy Angelhologram's article out of Immediate help, print it up and ask your folks to read it when they have a moment.

Perhaps you can work out a deal with them to get some straight ammonia, test kits (if you don't have them), a gravel vac and whatever else you might need for your tank.

Each family would work something different for themselves, so I surely don't wish to presume. In some families the kids would work around the house for some extra money. In others, it might involve lawn mowing or baby sitting elsewhere. Still others would have other responsibilities and just have to wait for allowance. While that is getting worked out, you, maybe with your folks, can do a fish-less cycling of the tank. Summer vacation may be an easier time for these things. :)

Again everyone's family will work responsibilities out differently. When our kids were about your age, I think my daughter kind of enjoyed working together on her guppy tank, where a pair of golden, red veil-tailed guppies became a whole tank full of gorgeous golden-bodied red-veils. My son had his tank of Fp. gardneri Misaje. He was delighted when a pair of his killies won a trophy in a show, while I got skunked. ;)
