Hello,
This is actually a serious interest of mine.
I am working on something similar but web-based. I can certainly make this work from a CD as well. I have all my source material (much of it custom written by me). I can also simplify the text for a younger audience.
For $200.00 I will give you the right to use it for non-commercial/educational use only. In other words, I am not granting you resale rights. Since this is an on-going project, I will also provide free updates for one year.
Best regards,
Shawn
