Excellent Free Business Research Site
Found an excellent free business research site that will help you decide what business to start, its a collection of free data of different market areas and businesses and tells you how much competitors are charging in that area, how many clients they get, plus helpful things like unemployment rates, area growth and so on. Its free and a great way to compare what business you should start and where to do it at. They also have a "score bar" which makes it very easy to understand.
Just google Market Role Model, and it should be the first result, or marketrolemodel.com
