I need help fundraising Please help?

I am 17 years old and a junior in high school and i started running an all girls dance club at the middle school. This dance club started out just as a place for free dance cles but now i am working on turning this into a place where girls can have a romodel someone to look up too. Being a preteen girl is hard. Society has set standards for girls about how much they should weight what size they should be and what they should wear. I want a place where girls can be girls a place where they can have fun and be themselves. Every girl deserves to have an older sister someone that they can look up to, someone they can talk too. RIght now we are in a small room at the middle school and all the gyms are taken but my big concern is we are working on performing our dance and having a performance night and i want every girl to be able to participate no matter what. If you have any ideas for a fundraiser please let me know Thanks sooo much.
