Jason, as you or anyone else gets sponsors to sign for the show, could you please ask your contacts to provide you with a high resolution (if possible) copy of their logo so I can start accumulating these to drop in over the course of time. It will be so much easier than trying to gather all these in the 11th hour. If they don't have hi res, send what thy got. Pulling them off a website is not ideal and is low res.
you can email them to me.
