Raising money for a school trip

Hi everybody. My name's Leah, and I'm trying to raise money to go on a school trip with all of my friends. We're traveling to Washington D.C. And to New York for 5 days, touring and sightseeing. I'm 14 and this is my first time doing any kind of fundraiser, so bear with me. I need $1,700 by November. I know it seems impossible but I'm not giving up yet! Every penny counts and it'd be a great help if you would consider helping me out. Thanks everyone.
