Suriname was formerly a Dutch colony and Dutch is still the official language there. Afrikaans is derived from Dutch so it should not be hard for them to learn Dutch—and supposedly English is widely spoken there (probably most of them know English). Suriname is sparsely populated (10 persons per square mile) but I don’t know if there would be any economic opportunities for the Boers there.
The Boers might even create economic there. But right now is a very bad time to be seeking our help. We can help you leave, but that is about all we can do at this point in time due to our own problems.
