You might be able to pull off the payments side using cryptocurrencies. Check out the CharityCoin directory for Bitcoin addresses: https://github.com/charitycoin/directory. You also might want to check in with the Stellar folks (http://slack.stellar.org/). They're working on some cool international projects dealing with financial inclusion, though there's a good chance you'll have to build the necessary connections to the Stellar network yourself.
