If you can provide task management like Franklin Covey system. I think you would have a system that is hard to beat and can probably charge more.
I will be doing a hybrid of managing my tasks through Franklin covey Plan plus online and ACT for all my Calendar and contact management. I would be willing to pay you what I pay Franklin every month if you can put it all in one package.
Your system for contact management is hard to beat but your task management has a lot to be desired.
