4 week Trip to peru

Hi my name is Jack I am 13 years old and I have been given the opportunity to go on a 4 week expedition to Peru. I will be staying in a local community helping them to become more sustainable in growing their own food to aid the reduction of malnutrition. Alongside this I will be helping build houses and community facilities such as toilets and the supplying of fresh water. This would be the trip of a lifetime for me and therefore I would be grateful for any donations big or small.
