Good day,
Your request is an interesting one and I would like to work on it with you.
The outline of my approach would be as follows:
1. Clarify your exact requirements and understand the rules of lotto wheels and their possible variations.
2. Research existing lotto wheel generators and/or existing white papers.
3. Derive our own mathematical model that satisfy your user experience needs.
4. Create the basic lotto wheel library in Python. Test it thoroughly.
5. Build the windows desktop GUI, including the user experience you want.
6. Develop the printing capabiliy.
7. Tweak the program until you are satisfied.
We can discuss breaking the payment into milestones, but I would accept 10% upon delivery of a mathematical model and program specification, and the rest upon completion.
I hope to hear from you!
Best regards,
Morne Potgieter
