Try arik...
They seem to be the milling house for every young kids fantasies. The CP at arik loves the dreamers. What tribe are you???
best of luck, however to be honest aviation in nigeria seems to be the rich childs game. Advice to you, NEVER EVER BORROW from Friends or many cases family. Ive seen many a person struggling with this.. Try and keep any borrowing to a minimum, try and get a sponsorship or bond to limit debt exposure.
Once you acquire your rating and licenses tell arik you are willing to go and fly the Q400 and they might send you straight for flight training :-) They seem to not put any pilots on that airframe from nigeria so therefore you could be the first.
