I would say your close on your estimate OTG. Mark is one of the most well known, and RESPECTED names out there. He is a great guy and has a certain way of teaching/presenting things so that everyone takes something away.
He is also extremely busy, and IMO, one of the most sought after speakers around. Supply and demand makes for a fat payday!
