Dear Sir,
I have read your Project Description and checked the attached PDF document, in which you have listed all the features with screen shots. Actually most of the features are doable as our team is experienced but I am afraid this is not a small project, so our estimate is way higher than your set budget of US $1,500.
Please let me know, if you are flexible in your budget, we can then definitely move forward, If not then no problem and I totally understand.
Look forward to hearing from you and talking to you further thru' Freelancer message board.
Regards,
YK
