On the sponsorship thing, there is a way of making players appreciate sponsorship.
I was laughing at Opie Logrun not so long ago. he has started a clothing line (Abtract), and is a cool kid. His stuff is good stuff and he is doing OK with it. But now everyone is just asking him for free gear all the time. Its killing him. Dynasty hate paying for anything, but now he is on the other side of the fence he hates it. While I was talking to him 4 different people came over and asked him for the 'hook-up'. I doubt that kid will ever ask for anything free again. Its been a revelation.
So do this. Have an Expo where each team has to buy a booth and sell a product (can be anything) that they have made/bought/spent considerable time on (they will have to get up at 6am to set it all up obviously). Let all the industry people arrive when they feel like it, walk around the booths complaining about the pricing and using every trick in the book to pay less than the asking price. Then send the sponsors of the teams round, demanding thier share for free, and saying things like "if you give it me I will use it/tell people its good/make it cool. Then, at the end of the day, when the teams think they might have actually raised a small amount of cash to help fund thier paintball, send the organisers of the event round to demand thier booth fee (they will probably want some free product too, as prizes or something).
After, at the bar, the industry guys could demand that the teams buy them drinks all night because they don't have any money on them, and when the teams are settled down and trying to have a quiet drink, the industry guys can hassle them for more free stuff, in a loud drunken way, until the teams give up and go to bed, only to be kept up all night by the industry guys having a party in the next room, completely drunk on the free beer the teams paid for.
how does that sound?
Sound like fun?
