I’ve been providing a simple ‘green’ service at commercial properties since 1981. Using only hand tools, I perform a daily litter cleanup service for the exterior property (sidewalks, parking lot, landscape). Almost as easy as going for a walk! I generate a six figure income yearly from this simple, home based, low cost start up business and I can teach you how to do the same. Details online: http://www.cleanlots.com.

Evaluate your talents. Keep in mind, there is a huge difference between talents and things you enjoy. Just because you enjoy something does not mean you can turn it into a business. Think about your skills, or the hobbies that you do better than anyone else. It could be baking cake, making jewelry, or stitching dresses. Your business can also be based off of a professional skill you've developed or been educated in.
A customer persona is a fictionalized representation of a specific type of customer based on demographics and interests. Typically, a business will have several customer personas if they are selling to multiple customer types. You need to figure out which customer personas fit your business, because it’s important to know the demographics you should target in your market research.
