You'll want to have a team meeting with players and coaches to discuss the details of your fundraising ideas. Figure out exactly how much money the team needs, and what exactly the money will be going for. If you get your numbers sorted out early, then you'll know exactly what sort of effort you're looking at with your college sports fundraising, and that can help make things easier.
Now you you need to find some college sports fundraising that will be appropriate for your group and its needs. You will need to take into account the size of your sales team, and the people you intend to sell to. There are ideas from candy bars to green fundraisers, so you just need to make sure that the fundraiser you choose fits well with your customer base. If you can get permission to sell on campus, chocolate bars can work as an excellent college sports fundraising idea, for example. It just depends on where you plan to conduct your effort, and to whom.
College sports fundraising activities are just a normal part of college life these days, but that doesn't mean they can't be fun, as well. Keep in mind that your team will benefit directly from this because knowing that there's a point to all of this can really help keep everyone on track mentally.
