Oscommerce XML Product Feed Google Merchants with Variants -- 2

I am looking for an oscommerce expert who has already worked on a xml version of a product feed (with variants) for google merchants. Currently, I do have a working copy of a xml product feed. What is missing is the attribute output for variants. As you will know - some attributes need to be output with a item_group_id - as seen here [login to view URL] and some attributes can be output as 'normal' You should have already worked on this and solved these problems. If you have worked on this, and you have a copy of a feed that works on a default install of oscommerce then please place your bid - please confirm that it works with variants and also variants that need item_group_id. Payment will be made instantly when I see this working. Please only bid if you have already done this work. If you want to bid to tell me that you can do it - then knock yourself out, go do it and post your bid once you have done. This job will be reposted weekly until satisfaction.
