Hi,
Typical website consists of screens for login, register, home etc and modules for authentication, authorization, error handling and logging. Based on the assumption that you're looking for something similar, below is what I propose
1. Website mock-up would consist of screens for user registration and login/ logout. Other screens include home and error pages. Any screens specific to your requirement could also be added.
2. Website to have a navigation bar to enable navigating between pages
3. Latest technologies including Asp.net MVC, HTML5, jquery, JavaScript, bootstrap, CSS 3.0 would be used. Authentication will be done using Asp.net identity which is OWIN based - this enables website to be deployed on any application server. SQL server 2012 database would be used for storing data.
4. Site will be secured against XSS and CSRF attacks.
5. Users can be restricted access to various pages using role management.
We could add/remove features as per your requirements. I believe this could be completed within a week. We can discuss in detail as needed. Thanks.
