Well I think he encourages people to email him, just google for mark cuban's email address. He gave an interview recently saying he likes it when people email him a small quick summary of what they are doing, why its big, what they need, and why cuban can help them

He reads all of his emails I think, he responded nicely to one of my friend's emails complaining about a post blocking the view from some mavs seats he bought.

Not saying you should expect anything, its a super super long shot, but its worth a shot, obviously he is interested in customer facing internet and might at least give you advice.
