Dear Toyosi,
I will insist that you get a good spot for your café, where patronage won’t pose a problem.
Isp provider – pls contact kits technologies ltd. Google their contact details from the internet. Their internet seems reliable.
Systems : Pentium 4 looks look good ( with config like ram-1gb, Operating system –windows xp, hard disk-60gb )
Generator: Pls. get a 15kva generator; options are – lista, mikano, etc. you can also look into some fairly used good Perkins generator.
I will advise you start with 20 systems.

I need quality companies who offer Prince2 training and PMP trainings. Infos about some companies that offers these trainings and success rate of their students will be appreciated.
