It is unclear to me who pays  this agency, and &quot;how much&quot; is more unclear.    I think that if I am your customer, it needs to be transparent to me...  e.g.  I know how much the end company is paying, I know how much my negotiator is taking, etc, etc.<p>Actually, that might be the closest we&#x27;ll get to my idea;  just start an agency that gets on the &quot;preferred vendor lists&quot; the usual way, then be transparent with the worker you are placing on what the fees are.
