Hi there, I have read your project description & sorry to hear about your current developer, so may I ask you to please provide me link of existing website or show me few design screen shots in JPG format? You don't have to send me PSD design for now, because right now I just want to finalize the scope of work, understand the overall features, so that I can give you my precise estimate in terms of time & cost to move forward.
Please let me know, if you want to see some of our past work, as mostly clients do not like that we post our developed website URL in the initial bid.
At the moment, my bid is just a placeholder, as I cannot submit the proposal without entering any amount but once you respond us, we can then finalize the estimate.
