Don't just hit the big companies. Hit everybody up for anything they can donate that will help. Take a look in the Fundraising subforum here and see what you can come up with.

For the NASA grants, read the information carefully. You need to make sure to apply correctly, and fulfill all the requirements. (I'll let Dave Lavery get more specific if he chooses; I think he already has in a thread on the NASA grants.)

As for the other companies, try going through their respective Community Relations departments.
