How to money as a High School web developer?

I am a senior in High School and would really like to turn my website making hobby into a paying job. I have already designed and updated a website for my school and have made multiple wordpress(.com) sites, with some learned knowledge in .org. I am a fairly advanced programmer, knowing a fair amount of multiple languages (PHP, HTML, SQL, Java, C++, VB, some Ruby, some Javascript to name most of them), but do not have the credentials (a college degree) to prove it. How can I take my ability to make websites to the next level and make money from it?
