Multi-store eCommerce

1. I want a eCommerce solution that supports multi-store. My definition of multi-store is a single ASP.NET application that supports multiple front-ends based on the sub-domain. All products should be stored in one single databse. 2. I would like to have as many features as possible from the lists shown here - [login to view URL] 3. The product has to be scalable and would like the least amount of effort possible in creating new sub-domains. I don't want to change the core every time I add a new sub-domain. Everything should be taken care of through configurations. 4. The database scheme is already available. If you need additional explanation please let me know. I will specify the details based on your response. This project is just a proof of concept. If it works there is a good chance of steady enhancements for a year or two. Beyond the bid and and amount of time, it would be best if you could send me a small working code that shows how you plan to configure the sub-domain programming. I am looking for someone that provides a good framework and coding. Language Requirements: ASP.NET (C#) 4 SQL Server 2008. Will need complete source code and proper documentation
