Integration File Project

ASP.NET 2.0 and SQL Server 2000/2005. Parts of these requirements require a GUI and other parts do not. Users are associated with a company that is associated with a URL. The URL just defines the company so we can use the same system and have different URLs. The company name and/or logo would be displayed (this can be in the DB and hard coded). User logs in and see's a list of Projects that they can run. Each project will have (new project, view history, and download import file definition). The new project consistes of uploading a file, a comment, running a validation against the import file, and creating an export file. This process is custom for each company and integration so this architecture needs to be built but not the actual code to do the validation and export. I expect to have a class for each client and its custom code for each project. After running a new project the export file is logged against the import file and a date. The user can download either one but can't recreate one. The history will just show the old projects that were run. Simple 2.0 GUI like base camp or community server. Can provide access to a non working demo.
