E-Commerce Storefront With Multi-Payment

I’m looking to launch a robust online store dedicated to physical products. The core objective is straightforward: shoppers must be able to browse items easily and complete checkout through a variety of payment gateways (credit cards, PayPal, Apple Pay, etc.).

Here’s what I’d like delivered within this engagement:
• A clean, mobile-responsive storefront—built on Shopify, WooCommerce, Magento, or another mainstream platform you’re comfortable with—that’s ready for me to load products.
• Integration and full testing of multiple payment options, ensuring smooth, secure transactions.
• A concise style guide and reusable page templates so I can expand the catalog without breaking design consistency.
• Basic administrative documentation (adding products, viewing orders, processing refunds) and a short hand-off call or video walkthrough.

I don’t need advanced search filters or user-generated reviews right away, but I’d like the codebase and theme structured so those features can be added later without re-engineering everything.

If you have a track record of building conversion-focused e-commerce sites and can deliver a polished, ready-to-sell storefront within a medium budget, I’d love to hear how you’ll tackle this and see examples of similar shops you’ve launched.
