My Volunteer trek to Cambodia

I am Ashleigh Heath and I am raising money to partake in a World Challenge expedition to Cambodia in November 2017. On the trip, I will immerse myself in the Cambodian culture, participate in a trek through wilderness and spend time volunteering in a local community. The money goes towards funding the trip and contributing to the local community I will be working in, in the form of buying products such as building materials. 

I need to raise the money by the 1st of August 2017. 

Any help would be greatly appreciated.
