Welcome to the Q&A Forum

Three websites = 3x the work...and budget needed. Similar to a medical clinic when it comes to services. List this company's services and optimize accordingly. If it is an incredibly competitive market, niche website may be the way to go. If I had it my way, in a medium to low competition market, i would focus on strengthen the content & DA on one site, rather than 3.

to be on the safe side, find a hosting provider in Africa. If you type in "franchise" in the google.co.za search engine, the majority of the first page listings are the .co.za extension, so even if the local hosting makes a small difference might as well take advantage of that.
