Add "size variation" to 110,000 active ebay listings

I have 110,000 active items on ebay and they are all the exact same item only with a different image and title. They are being offered at a particular size and I would like to add 2 additional sizes which will add to the cost if the item. This will require the item description to need to change also just a bit. Please quote me your best price on how you can do all 110,000, how long it will take and how you plan to accomplish it. I am not interested in relisting the items, I just want to add the variations to my existing items. Here is one of my items being offer at 4x18 inches and I need to add a 6x24 and 9x36 inch option.
