I have understood the initial high level requirements & visited the website but may I suggest that we schedule one to one technical meeting to discuss everything more in depth, as it is important to make sure that we are both on the same page in terms of requirement understanding, after that we can finalize everything to kick started.
So, please click on the chat button to schedule a meeting time, after that I can revise our bid.
Look forward to hearing from you.
