T-Shirt eCommerce Website Creation

I am in need of a talented web developer to construct a user-friendly, appealing online store for my small range of 0-10 t-shirt designs. I'm open to suggestions regarding the platform, given that I skipped this aspect when envisioning the project - WordPress, Shopify or Wix experience would be beneficial due to their robust ecommerce support. It's imperative that the website includes an integrated payment gateway for smooth transactions. The ideal freelancer for this project would be one who has proven experience in ecommerce website development, understands how to create visually appealing and easy-to-navigate websites, and has knowledge of secure, reliable payment gateway integration.
