Create Google Shopping file for Volusion based website

Need programmer skilled in Volusion shopping Cart to generate a working Google Shopping file for our website. We already created one using the Volusion API. However, only a few products were added as Volusion support said there are a few fields that are missing in the other products that are needed for them to be included in the Google shopping file. So, You will need to Import these fields into the remaining products. Once that is done, generate a complete Google shopping file. This is a simple project if you know Volusion shopping cart. So please, unserious bidders, random bidders or marketing reps, please do not bid. State I AM A VOLUSION PROGRAMMER"
