Who do I ask for help with my charity ?

last year I made a huge move across the world to Zimbabwe and I have been devastated by the poverty and political turmoil that I see every day. I came here with a very open mind and I now feel I am starting to lose hope. I have fallen in love with a tiny town called Nyanga and I am trying my hardest to help at the local hospital and orphanage as much as I can. The hospital has almost no staff, no I V fluid, no plaster, face masks disinfectants etc. All the basic requirements are missing and yet the people that work there do it with so much pion and sacrifice. The orphanage has broken my heart, the children are sleeping on the floor and only have one set of clothes each. I really don't know how I am to make a difference by myself. I have emailed soooo many churches and had no replys. I have plenty of time and motivation but no finance. Please suggest something.
