Copy items from eBay to website

I am Looking for someone who can copy all my eBay listings into my cubecart 4 eCommerce site. All off the photos will need to be copied and the description of the item and put into the website. Some items are already listed in the website, so care will be needed not to double up the items. Price will need to be entered, and that will be the same as the eBay price. Postage also will be determined by the price in eBay. Knowledge in SEO would also be helpful, as this can not be copied and will to vary depending on the item. Approx 2000 products will need to be copied, but this is made slightly easier due to the fact that there are 16 of each item, just the team varies.
