Analyze some Data - amazon product verification - open to bidding

We have 17000 items in our inventory, that we have listed on our amazon store. the work involves to check these items (skus provided in excel file). against the amazon inventory and make sure they are listed against the correct item on amazon and adjust price. e.g. we have a an item that is "1x pack of cereal bars." our inventory item is priced for 1 piece. But the same item is listed on amazon store in a box of 12. So in this case you will delete the amazon inventory item and list it against another listing with 1 pack size and change the price. More than 90% of the items will be listed against correct items on amazon. So they will not require any change. you will only need to be verify the item and price will need to match the second lowest price on amazon. Expectations: 1)check each item manually on amazon, to make sure its listed against the correct page. 2) Adjust prices for each item to match second lowest on amazon. Work needs to be finished by sunday. Low bid will have priority.
