I heard a story about an Irishman once. He finished his CPL/Multi IR, sold every thing he had at home and he said...
"Im going west. Im going to carry on going west until I find a job"
6 weeks later and half way accross the pacific he got a job flying Beechcraft in Guam. I believe now he is back in Ireland sitting in the left hand seat of an ATR 72.
I am half way through my JAA course and not really bothered about trying to get in the right hand seat of a 737 straight away. Id rather just go somewhere and find a job flying any old thing any old place. It may not be the most glamourous of jobs, but it gets the hours up, and I bet its a whole lot of fun. I have spoken to people who have packed up a good job flying jets in the UK to fly twin props to places in the back of beyond. They say they wouldnt give it up for the world.
If I were you, and all done with my licences, I would get a ticket to some place, turn up on the doorstep of a company and ask for a job. Its been done a lot.
Cheers
Have a read through the African forum. There are a few stories of how folks got jobs over there, by going down and asking for one.
