d_gun,

though your intentions 'may' be sincere and good, one begins to feel quite offended with all these your 'fool, n idiot's. u really don't know who are addressing in a forum like this, be it jobs/vacancies or whatever. I'd advise that u watch your temper,

In case u haven't, please visit https://www.nairaland.com/nigeria/topic-1026.0.html for our rules, they include,
1. You may not bully a fellow Nairalander (1st sentence),
2. NO PERSONAL ATTACKS OR PUBLIC FIGHTS,
it's obvious u have voilated at least these two.

neways, folks, i believe such certifications, again 'may' help in one way or the other. the fact remains, there are not guarantees! u will still need some relevant skills, backed up wiv some sort of paper (degree/diploma etc) qualification(s).

I wish everyone favor in his/her search for livelihood.
