Simple website project needed immediately

I need this page duplicated:
https://www.thedrinkexchange.com/square.php

Specifically I want to this page to appear when users visit:
https://www.thedrinkexchange.com/square

In other words, I want to keep the current page at:
https://www.thedrinkexchange.com/square.php

And I want to duplicate the page so that it shows up here:
https://www.thedrinkexchange.com/square

I need this done right now.
I'll give a 10 rating for good work
