Where Can .Orgs Go For Sponsorship?

Greasy311 asks: "A group of people from #windowmaker on irc.openprojects.net have just registered to run a booth for windowmaker.org at the .org pavillion of the Linux World Conference and Expo in New York City. We have been thinking of ideas for some type of giveaway and would like to do business card sized CDs with a tour and information about Window Maker, themeing, and graphical documentation on it's use, as well as some basic utilities so it could be used as a bootable rescue disk. To us, this is something that is very usefull as well as a way of gettin Window Maker some exposure. But the problem is we have no way of paying for the media and packaging. How should we go about finding sponsorship to help us with funds?"
