35 corps, maybe 2500 - 3000 performers & staff and admin directly involved with the event. I find it hard to believe that 4000+ tickets can't be sold for these events with a minimal amount of word of mouth marketing by all those with a stake in the game. Have each corps sell a block of 50-100 tickets and your almost there. Make it a fun weekend getaway, fill a bus with fans, include tickets for all the events in the package and throw in a t-shirt. Bam!
