Like said above the little sponsors can go a long way. Instead of holding out for one large company go to every local business you can find. I don't know the size of your team but lets say you only have 10 members and each one gets $200, that's an easy $2000. I say easy because most every local business would be willing to part with $50 for a little incentive. Make a poster with the companies logos and put it up in your pit, put top 5 businesses logos on your robot, send them something at the end of the season telling how their money made a difference. They will really appriciate the last.

It won't be easy and you'll get turned down a lot, but people that donate one year will tend to donate the next. Don't count on the one big sponsor being the life blood of your team.
