Become a freelancer?

Hello!

I am a web developer who has been developing for nearly two years now. I know multiple back-end languages, front-end(HTML, JS, CSS) and have been creating many projects with the LAMP stack.

I would like to become a freelancer, but do not know how I would find clients, or even if I could.

Should I even risk my time to do this?

Also, I am 17(incase that is a factor)

Thanks in advance to all responses.
