Hi,
This will either be very manageable using pyinstaller, or almost impossible. I have converted a number of my own apps into windows 10 exe files for clients. The only time I have had problems has been with python frameworks using complex library structures (django with multiple changing apps). So, if you can provide the python code or a testing environment (eg a windows VM) I can see if it is an easy build process. I suggest that you send me the outline and we chat and I can then see how it looks. I do not like accepting impossible projects , so I am a little cautious about guaranteeing an outcome in this case. But then I will not charge you either!
Best regards
Mark
