Convert small .NET file/app to PHP

I have a small .ascx (.NET) file that is about 300 lines of code that I need converted to PHP. The application is small and functions as a zip code locator, where you can type in an address and it returns a store location closest to that address. You will need to provide a PHP script that replicates the exact function of the .NET app. I need the work carried out within 48 hours.
