Dear Sir,
I have read your project description & understood the initial high level requirements 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. Do you want only IOS App or Android too? Do you also want WebServices?
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.
Regards,
YK
