Payment-Enabled Clothing Landing Page

I run a retail clothing brand and I need a single-page site that collects orders and processes payments smoothly. I’m open to WordPress, Wix, or Squarespace—whatever you think will serve the goal best—just no Shopify, please.

Here’s what I have in mind:
• A clean, on-brand layout that showcases a small product range with clear pricing.
• A secure checkout section connected to a mainstream payment gateway (Stripe, PayPal, or similar) so customers can pay without leaving the page. SQUARE
• An order-capture flow that stores buyer details for easy fulfilment and sends automatic confirmation emails.
• Mobile-first responsiveness and fast load times.
• Basic SEO set-up so the page can start ranking right away.

Once the page is live, I’d appreciate a quick walkthrough so I can update text or images on my own. If you share my faith, that’s a plus, but what matters most is solid experience building high-converting, payment-ready landing pages.

Please let me know which platform you’d pick, which gateway you recommend, and how long you’ll need to deliver the finished, fully tested page.
