Happy New Year NairaLanders.

Around December I started thinking of a business to set up on Campus. I am a student, normally I do term-paper for students since my 100level.
So I decided to go into printing and Photocopy after the new year break.
I want to get a laptop and a printer for a start, not necessarily brand new ones.

Here are my questions.
What kind of printer or laptop is best for this business?
What are the challenges?
How lucrative is the business?

Other business suggestions are welcomed.
Thank you.
