Greetings sir,
I have read your project description, and I've entered the average bid based on previous work experience with website design. But we'll need more information. Syncing website with databases, payments online, log in features, etc, as well as the design of the website itself, of course the more resources you provide in terms of design, the less time it will take, thus final bid would decrease.
Do bare in mind final time frame or possibly the bid could variate in terms of time frame as well as fee if project's complexity is exceeding the initial bid.
Free demos are our good practice, so we could offer a one. It would help you, in your review to help reassure you in quality of the product we offer.
