We are technology educationist. We want to get a site developed in c#, asp .net and flash which have following facilities: 1. The user is able to access course based on username and password. The course access can be limited by duration or number of logins. 2. The user will get course list they have opted and on clicking it they will get chapters list. Or if they have earlier logged they can start from where they left. 3. The course will contain running text material with heading etc. it also can contain as well as flash based video or flash based animation and can run into several pages. We also require conttrol panel for that. 4. User should have the facility to interact with teacher when teacher is available through text chat, video chat or audio chat (we have FMS 3.5). There should be a "white board" also for discussion with facility to paste graphics also on that. All these should be accessible to registered user basis on the option of chat either all or any one or two which they have selected. 5. Forum facility to registered users. 6. There will be test facility where user can go to the next step if clear it. It should also have facility where user can also be provide free access without test results. Kindly give reference to your already done projects of similar nature if any. We also require source code along with logic flow diagram. But you can also quote for maintenance separately incase if we will need it in future.
