Shopify Store Developer

Shopify Store Designer / Developer for clients who will be selling on the Walmart Marketplace. I have many clients who require a Shopify Store to help the Walmart Marketplace Application process, too many for me to handle myself. I am looking for someone with expertise in the Shopify platform, who understands Shopify's Walmart App and has had a proven track record of setting up Shopify Stores for customers who are selling on the Walmart Marketplace. I have a product listing for these stores, which will be need to created as products in the stores. If you feel this is a good fit for you, please apply with some up-and-running stores for your clients selling on Walmart where you were the designer and the developer of their site. I am also interested in other platforms such as BigCommerce.
