My team was in sort of the same situation after having won the award at the Washington, DC Regional. I'd absolutely suggest perusing other sponsors and donors in addition to the ones that currently support your team.

Check out this white page search from this website. Here is a second one too.My team took a look at all of these excellent examples and created a sponsorship letter and bracket system of our own. It never hurts to ask companies in your area for donations. Talk to you students about how to approach these companies, send them out, and see what happens. Keep in mind that you will have until Tuesday to make a decision, that's how it was for my team after our regional. It's a little tight, but really try to go for it. Good luck!
