Training young and old alike on the basic operation of a computer is a solid core business product for a computer tutor and this niche alone can provide you with an exceptional income once your services become well known in your area. 

Social Media training is another primary building block for all those engaged as computer tutors / trainers and is especially applicable as a course for the retired and elderly.  Learning how the use and navigate social platforms such as Facebook, LinkedIn, and Twitter can mean seniors can connect to a new and important pastime but training on best practices for getting the most from these platforms is essential.
