When the meeting? I would say that you should try to make kind of a collage. Include the words Coopertition & Gracious Professionalism, FIRST. Grab some of the images from the FIRST website (there are ones of Obama and Miss Daisy on the home page), include the FIRST logo (a big one) and lots of crowd shots. I know at least for the Florida Regional we got a lot crowd shots and FIRST seems to use crowd shots a lot.

You can also ask other FIRSTers for testimonies or something. I would say since the team is just starting out, to do regular paper (like the 8 1/2" by 11") to save money unless you are able to get some posters printed (maybe at Wal-Mart?) or pass out papers. If you need any help, you can ask me.
Another idea is to just spread by word of mouth and maybe try to get on the morning announcements or a lunch announcement.
Good luck! Can't wait to hear how it turns out!
