Hi vijay,
We've recently joined Freelancer and looking to extend our client base, we're currently working with clients globally. See our website vertextechnology.co.uk. This is a system we would be interested in working on. Its a nice straight forward requirement that I personally would enjoy working on. I would recommend going with Angular JS instead of Knockout, Angular is also based on a front-end MVC architecture pretty much, so ties in really nice with MVC and Entity.
We would go with and ASP.NET MVC architecture using Entity Framework and SQL for persistence and data modeling. For the user interface we'll use AngularJS for speed and live performance mixed with Kendo UI. Check out KendoUI, we're licensed and it's controls are really nice and clean, we have MVC wrappers also.
We'd like to work with you on this. Give us a message if you would like to discuss further.
Regards,
Ryan Smith
