alt Hacker Newsnot sure if right for your project, but an idea ive had in the past is that the organizations should have the jobs filled by people from the places they are organizing support for.
too often the work involved in taking it to an organization level is written off by the doners, and / or taken advantage of by the org. but renting a building and hiring people to take calls, perform accounting, etc has real cost that cuts into donations but it is also an area of job creation. Those jobs created, imo, are incredibly important and when they are given to people in the donating country it turns into mostly just economic activity in the doner country run on donations with just whatever amount is leftover going to the actual aid. of which, without any outright corruption, people are always eager to spend that money to make the organization side of things better.. or invest it into the organization under the guise (genuine or not) of scaling the organization such that donating a bit less today leads to more donations tomorrow. and then it becomes like any other business mostly running on debt and the actual donations are like a material cost that is constantly pressured to be cut down to pay back debts
I completely agree with this and its what we are doing already actually. Currently everyone is volunteering and all the money goes to the kids (except for bank transfer fees). I mentioned in another comment how much help I've received from the local community and the schools which has made this whole thing work. My thought was to hire Anwarite after she completes her education (if she wants) and start employing local Tanzanians as the project grows.
As a side note. I was once in a remote part of the Caribbean. When I was there I saw a shack selling Tom's shoes (the ones where if you buy a pair they donate a pair to someone in need). It seemed to me that Tom's shoes had donated to the local government, who then sold the shoes to a merchant who was selling them at this market. That means the local cobbler was basically out of work while the shoes were being supplied, and other shoe venders were losing out on sales, overall having a negative impact on the economy. On top of that all, Tom's shoes are very low quality and the pair they donate is even lower quality so within a few months they would wear out.
