Europe Educational Trip

I am a sophomore in Community Charter Early College High School, and my AP Europe History class, as well as the Art and French classes have organized an educational trip to Europe this coming June.  I have been fundrarising by selling chocolates, potato chips, water and sodas, and even done a zumbathon, but I am still need to fundraise $2,800 by this February 27th, 2014. Would you please help me? I really want go to this trip and my mom is a single mom doing her best to support me.  Thanks in advance for your support!
