What kind of business are you referring too, online or offline business?
To help you decide what kind of business to get into, personally, I would recommend getting into a business that you are familiar with, have some kind of expertise in and (probably most important) something within your budget!
I recently been thinking about and researching, leasing a few of my domains with developed sites (social media etc) on my own hosting site. Kind of a "turnkey" site..
I know a few local people (potential customers) who would love to have their own presence online but have neither the skills, patience or time to develop a site.
Currently. "crushing numbers", don't want to come across as "too pricey" or cheap, just trying to find a good profit margin..
