bearcroft, there's a school in SA that offers a 'cadet scheme' for someone without the cash. Working for them doing refuelling, menial stuff in exchange for 2 years during which he/she gains SA CPL(A).
More details on Avcomm. I think it's closed, but interesting to see something of that kind. It's not free, but way to 'get there'.
Your location states 'Kenya'. What passports/residencies do you have?
It could make some difference. Anyway, chances are slim, but do keep looking. I wouldn't have high hopes for countries you don't have right to live/work in.
The only exception I can think of off the top of my head was Etihad. They were recruiting non-nationals in the past. No idea how it goes these days.
