What are quick and easy ways to make a couple thousand dollars within a few months time?

I want to go to Japan this November and I’m having trouble raising enough money to go. I would like to attend a very special spiritual event and altogether its going to cost in the range of two thousand dollars. So I’m really trying to find ways to scrape together the cash.
I’m currently waiting on my 15th birthday to pass so that I can get a job at a local fast food chain. However I’m not sure that I will get a job there so I’m trying to think of ideas that can help me raise the money. So really any suggestions(except for car washes and other typical things like that) would be welcome. :)
