Dear Sir,
I have read Project Description & the websites you mention are big, when i say big, I mean to say that there are lot of features, while you have set your budget to US $1,500. May I ask if you can list down all the features in a document? This way, I can easily give you precise estimated cost.
Yes, I am ready to sign the NDA, so please send me the NDA.
Our current bid is just a placeholder to submit the proposal, as we still need to finalize the scope of work.
Look forward to hearing from you.
Regards,
YK
