Agree with Bert. Seems very fair and attractive from a business angle.
I would request making available advanced help from AC programmers with specific issues that prevent busy practices like mine from migrating to AC. By all means charge a fee for these services but please,please respond to queries from potential customers!
example: let us say $ 750 to help migrate a schedule file in a CSV to AC Scheduler, $750 to allow user to assign unique chart number and hide the chart-numbering used by AC... $1200 to do both and so on..
