Hi,
I already have fully functional python code using Google cloud Vision API which I can show you demo in couple of hours when I am back home.
I can help you with your GCP account and vision API credentials. I had a slightly tough time when I did it for the first time, but now you can benefit from my experience. I can do the entire process in a couple of hours for you.
The API returns a JSON and additional processing must be done, which I have done it too.
The code is fully functional and tested and ready for use.
Looking forward to talking to you in chat. Once , you contact me in chat, I can attach a demo video for it.
