E-Commerce Website, Card Payments

I need a clean, conversion-focused e-commerce site built from the ground up. The core must include a smooth shopping-cart flow and a fully secure credit/debit card payment gateway.

The store will launch with a small catalog, so performance and simple navigation are more important than heavy custom graphics; a responsive layout that loads quickly on mobile is essential. I already have hosting and a domain, so you can work directly on my server or develop locally and migrate once everything is tested.

Please handle:

• Modern, lightweight design that matches my brand palette
• Product-category pages, individual product pages, and a persistent cart
• Integration of a mainstream card processor (Stripe or similar) with SSL in place
• Basic admin panel so I can add or edit products, prices, and images myself
• Essential SEO tags and Google Analytics setup
• Final deployment and a quick walkthrough so I know how to manage day-to-day tasks

Optional features such as PayPal, bank transfer, or user reviews can be added later, so structure the codebase to keep that door open.

Acceptance criteria: every product must be purchasable end-to-end with a test visa/mastercard, orders must appear in the admin panel, and the site should score at least 90 on Google PageSpeed for mobile.

Let me know the framework or CMS you prefer (Shopify, WooCommerce, custom Laravel, etc.) and the estimated timeline for design, development, and hand-over.
