Britney (and anyone else in a similar situation) -
I highly recommend contacting your Regional Director if you are stuggling for funding... Actually, I highly recommend contacting your Regional Director just to introduce yourself.
The Regional Directors can be a great resource for many things. While they are typically over worked and very busy, they can help you sort out things like sponsorships. They may not have immediate leads or funding for you, but they may know of organizations interested in sponsoring a team or may be able to find some as they go about meeting new people and organizations.
You can find your Regional Director on FIRST's Contact Us page:
