If it is really only two way country transfer (or one receiving country and several country stacks sending money there) it would be best to build your own custom solution.

Basically a simple SW to allow for receive electronic transfer money in some region (one for EU, one for US, one for Australia for example) together with API linked bank accounts and one payout in target country.

Of course you might have to do some KYC/AML/PEP checks but there are API avaliable services to do that for you.

Depending on how you want to build it, it should not cost you more then 75k USD total.

Ask around for good SW houses in your area or call me and I can help you put it up together.
