I can't really tell the cost to start a small business, well let's say you want to start selling shoes and some clothes in this case I think you will need up to hundred thousand naira to start up the small business, or if you are going for food stuffs that is selling of provisions like rice beans etc, you will need like 50 thousand naira to start up with, the cost of starting up a small business all depends on the kind of business you want to start up with.
