Trekking and improving life in Cambodia

In 2016 I will be going on a self-funded school trip to Cambodia for one month with an established trip oragniser/volounteer based project group called 'Camps International'. Within the month i will have the opportunity to meet locals, help improve living standards within Cambodia,improve the wildlife by planting trees and educating the local children; but also having the opportunity to experience a 5 day trek though the dense jungles of cambodia, which is an amazing opportunity. I hope to meet the target of £800 with help from you, as all the money raised goes towards helping those in need, it goes into buying resources to help improve living standards, and ensure my trip is safe and filled with experience. My overall target is £3,400, but i felt setting a smaller target would be a great opportunity to recieve a helping hand from those who feel what i am doing is worth supporting. Any and all donations are very much appreciated, Thank you!
