Website for market

I'm looking to get a website built that will power an e-commerce marketplace. I currently have a hosting and domain already setup, and am looking for a minimalist design that is user-friendly. The platform should be able to showcase products, facilitate payments, process orders, and secure data. Ideally, the website should have an intuitive navigation which makes it easy for customers to browse and purchase products. Additionally, customer service should be a priority with features like refunds and support tickets. The website should also have search engine optimization (SEO) to make sure it is easily findable online.
