Build-A-Sign style .NET web application(repost)

I need the code for a module that will allow me to add to my .NET based web site functionality like that found in [login to view URL] I need it to be able to store all of the information about designs so that they can be re-generated at a later date. I need to be able to upload logos from multiple file formats, including EPS, JPG, TIF, BMP, GIF, PNG. PDF would be nice as well. I do not need any of the shopping cart stuff. Just the .NET module and source codeas well as copyright control. We would like to see a rough prototype of this functionality before picking our coder and expert guarantee. One of our sites is corpconnect dot com.
