Dear Sir,
I have read your Project Description & understand the initial requirements, so do you want only iPhone App or Android too?
Please drop me a message thru' Freelancer PMB, so we can discuss everything more in depth to finalize the contract.
As you know that without having detailed requirements, we cannot estimate it, so please ignore our current bid, as it is just a placeholder.
Look forward to hearing from you.
Regards,
YK
