How can I raise $1,200 over two months to go to Italy with my orchestra and choir?

Next spring, my school music department is taking a trip to Italy, and we'll be performing at historical landmarks and touring Italy. My parents are worried about it, since not many people we know are going, and it costs almost $4,000 without spending money. Since we'll be going on two pretty big family trips in the next 8 months or so, they don't really want to pay for it, but they said if i can raise $1,200 over the summer, I can go. I realllyyyyy want to go, so if you guys could suggest creative yet realistic ways to earn the money, It'd be a hugeeee help! And it has to be over a short period of time, since I'm superrrrr busy during the school year. Thankssss(:
