From what I know, my team was made up of two of the schools in the district. Now it's only my school, and looking at the back of my t-shirt, we have three sponsors other than my school(one of them is called "the cad store" and I asked what in the world that was, but no one gave me an answer yet).
For in-school fundraisers, candy is popular. I myself sold 70 truffles bars this year(10 sold on an average day). All I did was carry a clear bag(like ziplock) of truffles to every one of my classes, put it on my desk and people would buy them.
I am really sorry to hear about your team's situation. My sister's school's FLL team(their first year) has disbanded because the teacher didn't find time to do it. As long as all of you, your mentors, and your teachers are willing to do this, you should be able to. So keep your hopes up!
