In short time I'll maybe start managing a bounty campaign. (in negotiation)
I hope you get the assignment, good luck for that.
To give you the feedback: It will be your management. You keep the right how you manage it. If the participants agree with your terms, you will hire them and if they don't then don't hire. I am sure you won't have the problem of not having enough participants. There are lots of members in the forum are looking for bounties.
