Looking for a Publisher

I've finished writing my children's book and I'm really happy with how it turned out. I've printed one copy, but I can't seem to find a way to publish it for free when I'm still a teenager. No one wants to publish a book by someone who's under 18 years old. I really want to get this book out there though. Maybe I'll get lucky.
