Loans
Benja,
If you have to take out "huge loans" don't do it. Save your money for something else. The only option you have in your own country is Air Mauritius which I am told is difficult to get into if you don't have connections.
As for Africa there is no guarantee. You will have to compete for a job like everyone else. Many people will have many more hours than you with more experience so it would be very tough. Your advantage will be that you have trained in Africa and know the country alot better than the bus loads of Euro's that go there looking for a first job. I assume you speak french so some African countries that are french speaking may bear more fruit for you.
Good luck
