Add in Cost of Goods Field to each product.

Hello, What im looking for is,
A vqmod/edit for the Back end of OPENCART, I wan't to add an extra 2 fields for each product.

A Cost of Goods Field, and a Fulfillment Field, added into the DATA tab for each product, is there a module out there that does this? or is there anyone that can code this?

The company i work for are willing to pay to commission someone to write/code this for us.

there's a module out there that adds a cost field
