All seems to be covered rotateandfly! As far as job opportunities, as you've read, you've got to get out here and start knocking on doors, which means bucks for living and patience in getting all relevant licences etc. Important to come with a multi IR at least. Guys have waited a year or more for an opening, others have pretty much walked in, right time, right place.
As far as experience, I'd still say you've got to start somewhere. Most operators aren't going to take you with 250 hrs and send you into a 250m strip of mud. If they do, then don't! Most 'tourist' ops operate into pretty good strips, and there's a good percentage of us with 182/206/210 time from low hours doing that. Once you've got that experience more stuff opens up.Know a coupla Canucks started off in 180s/ 185s in Northern Canada and Alaska, floats and skis etc, good experience, and probably wish they had either one or the other attached for some of the mudholes you find youself trying land in later on! Worth looking at since you're there.
Certainly if you've got the time, hours, patience and bucks to find yourself something here, a great way to make a living. Also worth thinking about what you'll be wanting to do later on, and what type of experience they'll be looking for.
Got a few contacts in Kenya, TZ, Bots, Uganda, Sudan, I'll pm you.
Best of luck.
Happy New Year to everyone!
