i want to work abroad

I am interested in working in Peru, South America. I was curious if anyone else had experience working in a developing nation such as Peru and what their experiences were. My wife is from Peru and I am well travelled, so you don't need warnings about all the typical cultural issues.

What I am looking for are words of advice on finding a company that has positions in foreign countries, how the work environment differs in different countries, compensation and anything else work related.
