D2C Mobile Accessories E-Commerce Site -- 2

I am launching a direct-to-consumer store that will start with phone cases and screen protectors. The goal is simple: sell these products online through a fast, intuitive shopping experience.

Shoppers must be able to
• search and filter the catalog
• add items to a cart and pay securely online
• create an account and track their orders afterward

Deliverables
• Fully responsive ecommerce site (Shopify, WooCommerce, or a comparably easy-to-maintain stack)
• Secure payment gateway with taxes and shipping configured
• Order-management dashboard for processing, refunds, and status updates
• SEO-friendly structure, compressed images, and quick load times
• Step-by-step documentation plus a short hand-off walkthrough so I can add new accessories as the catalog grows

Please include links to similar D2C sites you have built and a brief outline of your timeline and process.
