New business website

We would like our website redesigning.
The new site is to be more customer and product orientated.

Since we released our Document Control System, sales have been via Phone and Word of Mouth, but we would like to drive interest/sales via the website.


There may be a future project to develop a Partners site for Partners to register & track their Sales & Renewals.


Requirements:
Must be built in ASP.NET

Environment:
Host - Windows Server 2008 R1
Database - MSSQL 2012 Express

Existing Site:
redplanetprogramming.co.uk

NOTE:
Full site source code will be required. We would like to be able make minor changes ourselves.


Please supply examples of previous sites.
