I just got off a gig working for someone who is like the king of customer acquisition. Very successful at it. Very difficult to work with. And this guy is only in his job because he was acquired in a buyout of his startup.

From what I've gathered, if you want someone in this role they need to get paid a LOT of money. If they are good they could end up making more in commission than all your engineers' salaries combined so you need to be prepared for that...
