A product picture to be touched professionally for Amazon listing

I have pictures of one product (Power Bank Charger for mobile phone) that will be added to the listing on the Amazon website for sale. I want the background cut out from the product and touched up to make it look professional and better looking. They must be in accordance with the Amazon specifications or they will get rejected.
In total i will upload 9 pictures to Amazon website listing.
See example of product pictures.
