We're not going after corporate sponsors. We are NOT a registered not-for-profit - we're too small/not worth it to register (according to my tax person). We're strictly going after local businesses - mom/pop type places. We've also got 2 other fundraisers planned: A car wash and bake sale/BBQ in May, as well as a youth kickball tournament for a Saturday afternoon in June.
My plan is, during my information meeting (before tryouts) is to show what our budget is (stands at about $1100 give or take) and challenge the girls to surpass that total. I do NOT charge my players to play. The only thing they pay for is their uniforms ($41) when they first join, then they pay for anything else they need on their own (cleats, etc.) All of our funds come from sponsorships, donations, fundraising, etc.
I was using the term corporate sponsorship to refer to all businesses. You do not have to be a registered 503c for a business to support your team, but it may give them some additional write offs if you are. Our HS booster club just completed the process.
Not sure what the plans are for your team this season, but high level TB team fees in our area usually run $1000-1500 per family with 12-15 players/team. A parent can figure to spend 4-5X that amount when they factor in private lessons, travel, hotel expenses. Going to a big National tournament at the end of the season can also add another $2000-3000/family. Lower level TB can be significantly cheaper when you eliminate a lot of overnight tournaments that require travel.
