This is a very, very bad idea in the US. As a 13-year-old, you can't legally sign a contract, and that has serious implications for both parties as well as your parents.

Edit: comment below is correct, please disregard what I said (although it's still a very bad idea to trick people into signing a contract with you).

That's not generally true, in US jurisdictions; minors can legally enter into contracts, but contracts with minors outside of certain limits are generally voidable at the option of the minor. And a number of states have additional rules which provide conditions which allow some contracts of minors which would otherwise be voidable to be binding if certain procedural steps are taken.
