SEO Friendly CMS/e-Comm Solution

Hi I need a skilled ASP .NET programmer to build a Semi-CMS e-commerce solution in ASP .NET 2.0 (VS 2005) It would need a backend where the user logs in to administer orders and add/edit products. It would need the ability for the users to add their own pages of text (stored in the database) and put product numbers in the text in square brackets (these will be replaced with product boxes on the front end) Each page needs to have its own meta data and SEO friendly filename (using rewriting to hide parameters) Using the pages in the database the site would need to automatically generate its own Sitemap whenever pages are added/deleted. Each product would need its own SEO friendly page name as well. And for all intensive purposes be treated like a page. All need categories and category lists. Site front end displayed using Masterpages and Themes. I'll supply the developer with access to Visual Source Safe and SQL Server. I'll supply a specification and more detail when required. The developer will need to work quite closely with me. Also - whoever does this job for me, I will have additional regular ASP .NET work for.
