What you need is your CPL and preferably IR, current medical alot of money and a pair of balls.
You've probably got all of the above so here we go.
Research the forums on bush flying and bear in mind you have to be at the companies door for them to give you a job with low hours. They have a special file for resumes called the trash can.
try Botswana, Zambia, Namibia, Malawi and Tanzanier. Talk to the pilots as you go around and you might get lucky.
If you have low hours though your probably better off trying to build some in Canada as an instructor or line flying in NWT first. More hours equate to greater chance of success.
