Voip rates display for customers

I am looking for a nice way to show my customer my current rates. I provide 3 routes for voip termination and 1 for sms. A good example of what I want is the rates page of voxbeam dot com the only thing to add is a search by country code. I will add this code to joomla with sourcerer or other custom code extencion so this code hast to complain with joomla so it doesn't break or anything. let me know...
