Wordpress Website Development

We are a business wanting to start a new WordPress ECommerce websites for a new product range. The person we are looking for must be experienced, completed other ECommerce stores and be able to show me proof of completed work. We have 2 other ECommerce sites that are almost completed that we want this new site based on. We also have 3 other WordPress Websites and a Magento Online store so having SEO skills and an ability to create more landing pages would be an advantage. Thanks for reading :)
