Dear Project Owner,
I carefully read your requirement.
But instead of doing all these manually, why not use automation such as iText or OCR?
We have effectively used such automation and then followed by proof reading.
We can provide you a free, no obligation proof of concept for the same.
I am Pranav Patil, representing Iristechsys Software Services LLP, an ISO 9001:2015 company based out of Pune, India. I have 15+ years' experience in the IT field.
Our company has a valid DUNS number and is duly registered with Registrar Of Companies, India - just to point out that we are not a fly by night operator.
My Linked-In profile will provide you overview of my experience.
