Changing Lives

Hey! I'm India, I'm 16 years old and I go to Hove Park Upper School. A lovely non-profit organisation called Camps International (www.campsinternational.com), take volunteers from prospering countries every year to stay in camps in poorer places such as Borneo, Cambodia and Ecuador, have asked my school if they can take some of it's determined students to Camp Tanzania, another of the companies camps. At these camps, the volunteers will be doing a number of wonderful things for the local community such as building schools and community centres, planting trees and helping to find ways in which the Tanzanians can create a more stable eco-system.
I will be facing the heat in the Summer of 2014 to help out those less fortunate and, in order to get there, I will need £4000. Most of this money goes straight back into the community as funds and money for building materials etc. A very small amount of it will be going towards my plane ticket and absolutely none of it will be going towards pay roll or profit. I think this trip is a very good idea because, not only will I be able to ensure my money is going to good use, but I will personally learn a lot of life skills such as determination, leadership skills and building skills.
This trip is a once in a life time opportunity, please help me get there.
India.
