Honest Opinions

Guys just came back from Nysc and i really need to start doing something starting with getting more qualification to be able to compete.
I thought i should start with the cheapest IT course which i feel should be CCNA.But the thing is that where do i get the cheapest school to study that  from at least 20k and below or should i just get the materials and read on my own and where do i get these materials.Speaking to all the nairalander gurus help these broda out with honest opinions
