What website should i use to learn more about how to become a professional singer?

With singing...you need to sing! Join local community theatre groups doing musicals. Join your school choir. Look at schools and private voice lessons.

Hello! They have so many sites.
I would suggest to have private lessons, but to begin, you have to be sure that you have the talent-voice!!

I can tell if you sing for me a few bars of a song, I can tell you if you have the voice.
but here is a website for you to check, good luck!!
