What certifications should I do?

Hi Pros,
I’m very interested in IT but i only have a diploma in Electrical and Electronics Engineering. I’m highly exposed to Networking(LAN) and computer maintenance.

I’m presently working as a cyber cafe supervisor in Nigeria but I want a career in the IT field and I don’t know which certification to start with. I will apprecaite your unreserved advice please. THIS IS MY FUTURE!!!!!!

Thank you.
Kay
