Im 22 and want to get back into dancing and do it for a living, but how do I go about it? I did ballet age of six and hip hop a few years ago.

Did you do competitive dancing? If so you can find a studio near you and see if they are hiring assistents. If they are that gets you back into the game and also a place to practice. From there you can compete again. After that you can look for job openings that you can apply to. Doing it that way you have references and recent video of your dancing for auditions.
