Dear Sir,
I have read your Project Description and I am afraid that Freelancer does not allow us to post contact information.
However, to estimate this project, we really need more detailed requirements, some reference website or we can schedule an online meeting. As you know that the cost of any website depends on the overall features or scope of work.
Of course, I can also send you some of our recently deployed Application as per your request.
Look forward to hearing from you and talking to you further thru' Freelancer message board.
Regards,
YK
