The words "Sales Professional" should tell you everything that you need to know. The income from Sales jobs is almost always based on the amount that you sell. So basically they've come up with ridiculous idea and are looking for suckers, er ah, Sales Professionals, to go try and sell their product or services but the Sales Professional doesn't earn anything unless that actually sell something. Also in many cases the potential Sales Professional is required to take, and pay for, expensive classes from them before they can start working.
