The big stumbling block will be their (lack of) right to live/work in a country outside of Colombia. It is generally quite difficult to attain this right outside of your home country and most companies can't or don't help with this due to the costs (both time and money) that are generally involved with trying to arrange work permits/visas etc.
Having said that, there are still a few options, but they're not going to be "Shiny Jet" jobs... For instance, Susi Air in Indonesia like pilots with FAA licenses... refer:

The pay is pretty crap until you make captain, the days long, the conditions can be challenging and management is "interesting"... but the flying is awesome and you can get a lot of hours and experience. They always have a lot of applicants, so it can be a bit "hit and miss" as to whether they bother responding to an application... and they'll probably make you jump through hoops and pay for things like online tests, trips to Indo for interview/sim etc. but it is an option.
Otherwise, perhaps have a look through the Botswana thread (
Maun, Botswana. The essential guide.)... again, this is GA-type flying (light single engine aircraft)... and is somewhat seasonal... but I know that some of the folks who are currently working there are relatively active on that thread and can offer up to date information.
