Greetings,
I have read your Project description & checked the Google Document, which I have forwarded it to my technical team lead, so please allow some times and I shall get back to you soon with our precise estimated Man-Hours.
Our current bid is just a placeholder since Freelancer requires it but once you respond us, we can then finalize the total cost & payment terms to move forward.
Look forward to hearing from you.
Regards,
YK
