Offering two people a free background check. In return, I just need your thoughts on how useful the information is, if at all, and how it compares to information you already have. If you're interested, just send a PM.
Depends on how and what you assign value. The information that would be provided would be valuable to me, but I would assume that even though everyone's time costs something, the two - three minutes that it would take to respond on the usefulness of the information would essentially equate this as a free deal.
