Adding Products in Magento Store

Hello - I am looking to hire some one who can add products in our Magento Store. You will be adding products and there are approx - 2K products . There are sizes mention which - I am going to use as an attribute or variant as an drop down, in size you will need to add an UPC code which is mention in my excel file, Item # will be used as product item number (SKU) - IN Excel file everything is setup as UPPER CASE - so when you add products you need to add them as Upper to Lower case for example if it says (CLASSIC 10 PEARL BUTTON CHEF COAT) - you need to add them as Classic 10 Pearl Button Chef Coat. When you add product you also need to add products images and and have them display as base image and thumbnail, each product is marked with Item Code if you are adding for example product 0400-2501, the image representing that particular product can be found as 0400, and that image will be then linked to that, You need to add the products to its appropiate category. I will give you ADMIN Access to do that, there is ZERO TOLERANCE SO NO ERROR - PLEASE
