I need an OpenCart Extension Modified

I have bought the UKSB Google merchant feed extension for Opencart. I have installed it and it works ok, but I have to manually enter the Age Group, Gender and color Attributes for them to be generated by the extension, I have already added these attributes to the products that I have in my store, and because I have almost 6000 items it it too time cumbersome to manually add this attributes to the products>Google Shopping Tab. I need someone to edit the php files in this extension that create the Google Merchant feed and the Bing shopping feed to pull the Age Group Gender, and color from their respective attributes found under Catalog>Products>(select product>Attributes Tab so this will not have to be done manually.

I will give you access to the backend of the opencart shopping cart system, ftp access to the files and a copy of the extension for you to edit
