First off, find what genre your voice fits in then put some videos on Youtube.
Then find an agent who will represent you and will help you find gigs but you can always start by singing at schools, etc.
The music industry is very hard so you must study how it works.
Know that it is all about marketing, so you have to see if you are marketable.
It’s easier to market a guy than a girl, and it’s easier to market a group/band than a soloist.
