I think I see what you want, but I'm sort of with Mike - your goals seem to be at odds - you want to provide an incentive but not make it too attractive at the same time. If money is an incentive, then people will flock to it, but that's not what you want. If the money is not worth it, then it ceases to be an incentive. Do you have an inkling as to whether the currently-absent experts would be interested? Seems like a bit of work if it fails to bring in the sellswords. The majority of us, I would imagine would carry on regardless, helping people for the sake of it.
