Publishers for teen writers?

ok so i'm a 12 year old girl (on my mom's account [with her permission]) and i submitted the first chapter and preface of my historical fiction/young adult book here and everyone loved it so now i'm looking for a publisher. If you're a publisher i haven't finished the book quite yet but i can send you the preface and first 1-2 chapters (it might take a while because i wrote it in a notebook, though). If you are or know of a publisher please inform me. Thanks!
