Apopka High Prom keepsakes and final cost

Hello,  I am trying to raise funds to help cover final cost to hold a prom  that will be on July 16th at The Highland Manor.  Parents have organized a prom for Apopka High School juniors and Seniors . Low cost  tickets are being sold to help  cover the cost of the venue, refreshments, and security. Parents and  teachers are volunteering to DJ and chaperone. I am building a photo booth for them to take photos. After all vendors are hopefully paid it leaves nothing left for a keepsake for the kids to take home such as a cup or keychain or something for them to take to remember their prom . I am really hoping to be able to get something for them. I am buying decorations and craft supplies for making decorations out of pocket.  I need help with seeing this through for these Blue Darters. If you are able to help in any way, thank you. There will be around 100-150 students attending, even $5 would buy keepsakes for two students and help wth final cost. Thank you for reading.
