Hi there,
I am Ahmed a Python developer,
i read your project requirements and I understand that you need a script to rename a bunch of files and folder, you mentioned that the script should work on windows, I can make that script i have already done similar thing and i will guarantee that it will works on Linux, Windown and MacOS
It will take for 48H to deliver the final work, you should test it and make sure that is works as expected
contact me over chat and let's have the work done.
