Hello,
We have a lot of experience with C#/ASP . We can even develop the website in ASP vNext (MVC 5) with Entity Framework 6 . It should be out of beta by the time we finish this project and it's the next big thing out there. We already used it in a couple of projects and it's stable and bug free .
We will also provide 6 month post project support which includes free bug fixes and small changes .
Our team consists of 4 programmers/designers with over 6 years experience and a vast area of expertise ( C# / .NET,ASP MVC, HTML5, CSS 3,Jquery, Flash, PHP, Java, C, C++,, Logo design, banner design etc. ).
Looking forward to discuss the details
Regards,
Andrei
