As I understand it there is not many options for lowtimers today. Most of my fellow pilots started as a CFI in the USA. I stayed on with the school i trained to get my hours up. This was in 1990 and I ended up getting 2000 hrs on the R22 before I got my first break and had the chance to move up to heavier equipment. Not sure what the tunaflying req are today in SouthAmerica but thats another route I took. Good money aswell but a bit risky. Good for building hours for sure, I averaged 8,2 hours per day on my first trip. Lots of lowtimers get IR today and become co-pilots. Don't just email companys, go there and show your face. Important to never give up and never burn any bridges.... you want it bad enough, you'll get it. Best of luck.
