Welcome to FIRST! If you have any mentors who are dealing with the non-technical side of your team (such as fundraising) I encourage them to
join NEMO (Non-Engineering Mentor Organization) as we can give them a lot of suggestions for helping the team in those areas.
Also, NEMO recently published two papers in the Chief Delphi white papers section which might help you out:
25 Ways Sponsors Can Help Your Team which talks about ways sponsors can help you OTHER than financially, and
Creating a Killer Team Packet which tells how to put together a packet about your team to take to potential sponsors!
