Add products to Amazon - 50 at a time

We are a printing company that sells stickers and wall decals on Amazon. We create new artwork every week and are looking for someone to do the following. - Create new products on Amazon (through seller central) - We will provide either illustrator or JPG files, which you will reference to create descriptions of the products - Some products will have options and some won't - You will need to be good at creating unique descriptions and keywords that are relevant to the product so they will sell. Please provide us a price per 50 products to add to Amazon. We will give you this quantity each time. Thank you.
