Woo-commerce Product cleanse and update

I have around 366 products in my woo-commerce webshop, with perhaps 50 separate products and their variations.

I need someone to 1) compare my product list with my three key wholesalers, and make sure the stock lists match.
2) remove any products that are no longer available. 3) add any new products, using the pictures from the wholesalers who have files of these available.

I would estimate around 3 -5 hours of work although you will probably be quicker!
