In the older days, program owners personally flew out and met up with people who could send massive traffic and wined and dined them.
I personally feel for huge accounts like this, it should be done if not by the program owner then an affiliate manager who knows how to have a good time boozing and schmoozing the potential client. Either that or find out what makes them tick and bring them a present, a good meal, and some business talk. Not everyone likes to party in this business.
I'm sure some programs still do this but very few if there are any do it regularly. It's a shame as that builds a solid relationship with the client and vice versa. This way you feel more comfortable doing busienss with the person as you have met them face to face.
