Starting a charity

Hello, so i have decided i would like to start a charity. Great, all good so far. the problem i have is i don't know how to get the money to the the people in need. I have done a lot of googleing and stuff and i can't find many charities like the one i want to start so I think it's a good idea, it's needed and there is not much out there like it.

I don't want to tell people my idea yet, because even if it is a charity and even if it's good if someone else does this, it's still my idea and i want to do it. because it's fucking great! But for example, let's say someone from England would start a charity which collects money to build a school in Peru, how do you actually get to build the school. I mean the actual building. Surely you can't just go to Peru and start building something.

If you want to build a house in Sweden you need shitloads of permits and stuff. If you want to build a house in Thailand you have to be from Thailand to own the ground the house is on. How does it work? Does anyone know? I have been trying to find out but i can't really find anything good and serious online, and you don't really know what's true and what's not.. 

If anyone know's please leave a comment.
