Hi David,
I have read Project Description & understand that this is time sensitive project, so please go ahead and send me detailed requirements first or at least high level features to estimate it precisely, because based on the project description, I can't estimate.
Please contact thru' PMB for portfolio or further discussion about your project, also, our current bid is just a placeholder.
Look forward to hearing from you.
Regards,
YK
