If I told you "Get me a 20 minute meeting in front of xyz person and I’ll give you $20 whether or not they buy into what i have to offer, would you set up the meeting?
Absolutely not. My ability to make introductions relies on people trusting me to make good introductions. If I make a poor introduction to someone it damages or destroys my ability to make introductions to them in the future. If I get a reputation for selling introductions I’ll lose credibility with everyone in my network.
