Digital Products E-commerce Website

I’m launching a small store that sells digital products only, so the site has to look polished, load fast and make checkout effortless. I need a complete e-commerce build—from the visual design through to a fully functional back end.

Core requirements
• Secure payment gateway fully integrated (Stripe or PayPal preferred, but I’m open to other PCI-compliant solutions).
• User accounts so customers can log in, view their order history and re-download purchases.

The storefront should be responsive, accessible and easy for me to update with new files and product descriptions. If you can suggest lightweight themes or frameworks that keep maintenance simple, even better. Once the site is live, I’d also like a quick walkthrough or short documentation outlining how to add products, change prices and view sales reports.

Please share recent examples of digital-product shops you’ve built and let me know your estimated timeline for design, development, testing and launch.
