Dll files in ASP site

I have an ASP.Net site in C#. The site was built using two dll files in a bin directory. Right now, the site functions fine but I want it to function without these two dll files.

The job is remove the dll files and the BIN directory from the site and make the two aspx pages work without them. It should be a simple procedure for someone who knows ASP.NET in C#. The original developer is not available this weekend and I need this done by Sunday night (tomorrow night).
