Hello Palacio802,
To covert your easa license to south Africa is quite simple, you need to go there, write a air law and procedures exam and do a checkride, this one can be done in any helicopter.
I have still sa validations and is quite easy, of course the cheaper way is a company sponsor you and pay for it.
For us, it is very difficult to get a job there unless you are a legal resident..
Buena suerte!
