Audition/Contest plugin

Hey!

I’m making a website where bands can open an audition to get new bandmembers. For example, a band opens an audition, and musicians can submit a video audition so the band can pick one.

But… I actually have no idea how to do this.
I was thinking about making 2 types of front-end users:
– Bands (who only can start auditions)
– Musicians (who only can submit video auditions)

What is the easiest way to do this?
