Will - World Challenge to Myanmar

I am Will a 15 year old going to Myanmar in December next year (2016) as part of a World Challenge team from Hutt Valley High School. We will be spending 4 weeks over there helping out the local communities in many ways: teaching them, helping with farming, building buildings and infrastructure. It will cost me $7500 and my goal is to have my parents pay as little of it as possible, hopefully none! We will learn life skills such as leadership, budgeting, teamwork and decision-making. The project is lead and planned entirely by the students and is aimed to challenge us both mentally and physically. We are planning it already and I am doing lots of different fundraising and looking for a job. I'd really appreciate anything you can contribute.
