Write some Software

I need to be developed an extension that can calculate the shipping on the product page of both single products and configurable products. For this, the module must integrate with Pedro Teixeira module Post Office - Brazil, to perform the calculation of shipping the products. I tried using the EcomDev module - Product Page Shipping, but there is only one problem with the calculation of configurable products. If you can just change the code in EcomDev module to calculate that it will be enough. I need him to manage the calculation in a popup if possible as Shipping Price Calculator from web experiment module that follows.
