I would say that a good start would be to get a meeting with multiple of your school administrators. Principle, Asst. Principle, Office managers, counselors, etc. and tell them what you told us. They can help in ways such as adding your team to the announcements, putting the team in printed material, and other "official" recognition. Preferably talk to as many of them as you can and get them to agree to help with your recognition problem (that may be a much easier thing to get them to agree to than giving you money)

Look around at the other teams and clubs at your school that DO have recognition. Are there signs about them in the hallways or on buildings? Are they often mentioned during weekly announcements? Are they mentioned in email blasts to parents or students? How do they get their recognition at Pep Rallies? (my school used to announce each team that came onto the floor, make sure you are part of that announcement!)

The first step of getting that stuff done is to get buy-in from the school administration and then KEEP ON THEM until the school publications are including your team regularly. make sure you don't just that task over the wall to them, work closely with them to build that recognition.
