After coming to Ghana as a volunteer I soon realised that most of the money I had paid to an organisation hadn't left England. In fact the disabled centre where I was working was losing money from having to pay for my meals and accomodation. I also realised how easy it is to volunteer in Ghana without any established organisation, which would allow you to spend the extra money on helping develop the project you are working on.
