You can make money using your Excel and VBA skills. I run a training company in Canada and Excel/VBA training and consultancy is our best earner. As a rule our clients like us to be certified to Master Instructor status, but in reality you need to be way above this level to consult. Get the word out to every company, computer outlet and any other organisation you can think of. Almost every company uses Excel to some extent and they always want help. Make sure you give quick, efficient and cost effective solutions and they will keep coming back. Develop a good all round knowledge of all types of business practices so that you can quickly grasp their situation and give them the best solution.
Good Luck.
