Physical Goods E-Commerce Website Build

I need a complete e-commerce website that lets me showcase and sell physical products online. The core goal is a smooth shopping experience from first click through payment and shipping confirmation, so everything from product catalogue management to order tracking has to work flawlessly on desktop and mobile alike.

At minimum the finished site must:
• Display unlimited products with images, variants and stock tracking
• Support a modern cart, secure checkout and popular payment gateways (Stripe, PayPal or similar)
• Calculate taxes and real-time shipping rates for my chosen carriers
• Give me an intuitive admin area where I can add products, update prices and fulfil orders without touching code

I’m leaning toward features such as user accounts, product reviews and live-chat support, but I’m happy to hear your recommendations on the best mix for conversion and customer service.

Please outline the platform or stack you recommend (Shopify, WooCommerce, custom Laravel/React, etc.), estimated timeline, and a short portfolio of comparable stores you’ve built.
