Streaming Platform Software in Python

I need you to develop some software for me. I would like this software to be developed using Python. I want to do a apps/website for whole plateforms (apk ios app exe linux) using the add-ons method.. like [login to view URL] check the app and let me know if it's possible ? We supply official add-ons on the apps like them = one for subtitles one for read video like .mp4 .torrent .avi .3gp (we can use VLC sdk) one for whole videos I can upload on a server The same officials add-ons like them And unofficials add ons For the officials we can copy there add-ons I think it's faster and easily than create new ones Tell me if you can do it and time and price Thank you
