There is already a funded training scheme: NATA has existed for years and is a partially government funded and partially privately funded by mostly German development sponsors. I am not sure how many candidates get selected to become commercial pilots per year, per class - bottom line is that only a very few actually make it to the end and are able to feed the market. In principle NATA has continuously failed to reach it's target numbers and goals.
NATA is the easiest and cheapest way to become a pilot, (even if your parents are rich - makes no difference you will still get funded), you just have to be a Namibian citizen and pass the assessment test and the door is opened for you. Under such beneficial conditions the output numbers are plain sad.
