eCommerce Store with PayPal Integration

I need an end-to-end eCommerce site that is ready to sell from day one, with PayPal as the primary checkout option. I am still weighing up Shopify, WooCommerce and Magento, so I will lean on your advice to pick the platform that offers the best balance of flexibility, ease of maintenance and growth potential. Likewise, the exact business model is still fluid—retail, wholesale or even a subscription element could all make sense—so the build has to accommodate different catalog structures and pricing rules without major rework later.

Key tasks and deliverables
• Install and configure the chosen platform, including products, tax, shipping and basic SEO settings.
• Integrate PayPal in both sandbox and live modes, then run test transactions to confirm orders post correctly to the admin dashboard.
• Apply a clean, responsive theme and adjust colours, typography and imagery to match simple brand guidelines I will provide.
• Supply a concise hand-over guide that shows me how to add items, manage stock and process orders.

Acceptance criteria
• PayPal checkout works end-to-end with no errors.
• Pages render correctly on modern desktop and mobile browsers.
• Meta titles, descriptions and clean URLs are in place for all public pages.

I will provide the domain, hosting and any premium themes or plugins you recommend and can move quickly once we lock the scope. Please outline your proposed platform, timeline and any questions in your response.
