I need money and I'm 13 year old from a small town how can I make money?

Well you see I have a seat reserved at this people to people meeting and if I can get the money I will be going to Europe next summer for like 20 days. I no they have financial aid but the problem is my family can barely afford to pay the bills let alone finance this trip that costs including money to spend while I'm over there approximately 7,000 dollars. I'm only 13 and I need a way to make a lot of money before then. Any ideas that you have will be considered and welcomed thank you! :)
