Rebuild specialty coffee storefront in Next.js with subscriptions

We roast about 40 tonnes of specialty coffee a year and sell most of it through a WooCommerce site that has become painfully slow and expensive to maintain. The plan is a ground-up rebuild on Next.js with a headless product catalog, and we already have finished designs and a content model agreed with our agency. Scope covers the storefront (catalog, product pages, cart, checkout), a subscription flow for recurring coffee deliveries billed through Stripe, and migration of roughly 1,200 existing customers with active subscriptions. We will handle copy and photography; you own everything from the design handoff to a deployed, tested storefront. Lighthouse performance above 90 on product pages is a hard requirement. We work async-first out of Melbourne, so clear written updates twice a week matter more than overlapping hours. Expect one 30-minute call per week and honest pushback when our ideas are bad - the last freelancer just said yes to everything and we both regretted it.
