E-commerce Mug Design Platform

I need a complete e-commerce website that lets shoppers create their own mugs online and place an order in one smooth flow. The heart of the build is a web-based mug designer: customers must see a live preview of their artwork positioned correctly on the mug, then proceed straight to checkout. When an order is confirmed, the system should generate a print-ready file and forward the job details to my chosen print-on-demand fulfiller.

Key points for the build
• Product focus: mugs only.
• Users design, preview, purchase in the same session.
• Print-ready output must match the fulfiller’s specifications (300 dpi, CMYK, correct bleed and wrap dimensions).
• Order management, payment gateway integration, customer email notifications and basic reporting included.
• Completion deadline: within one month from project start.

I’m flexible on the tech stack—Shopify app, WooCommerce plugin, or a fully custom React/Node solution—so long as the final site is responsive, fast, and easy for me to manage without coding. If you’ve built similar online product customisers before, let me see them and tell me which parts you coded.
