That to me would be the biggest pitfall, so any hiring would have to be managed by an independent third party, which would mediate in any disputes, but would also add to the costs.
A mate of mine from Carlisle has two sons who are trying to become actors. A lot of their acting school mates have been involved in the Northern Soul film, and are obviously trying to get as much exposure / experience as they can in order to increase their career prospects. I believe the girl with the Afro is one of these. This might explain things better.
Don't know if this will lessen the pain......

.......and I wouldn't advocate giving your dog away.
Four promoters, each sat in a swivel chair, facing away from a set of decks. Each young hopeful would then play their set in the hope that one or more promoters turned their chair round. I think you might have something there.
Cheers Dave, I stupidly clicked on the Amazon link and now they have lots of recommendations for me based on my viewing....."Now That's What I Call Stomping" and "Northern Soul Workout Mix" to name a couple.
