I already have a PHP-based store that is sitting on my AWS server and is roughly 90 % complete. Unfortunately, I no longer have the source repository or documentation—what you see on the server is all that exists—so you will be working directly with the live files. The main priority is to finish the design layout for the checkout process. Visually it is almost there, but the flow and steps feel rough: screens do not advance smoothly, field alignment is off in places, and a couple of review/confirmation pages are missing. I need a clean, intuitive sequence from cart → address → shipping → payment → order summary, with solid UX and clear error/validation messages. At the same time the domain connected to the site has been shut down. I will point a new domain to the AWS instance and need your help updating every reference so that the store loads perfectly under the new URL and all internal links, assets, and redirects behave. Key deliverables • Revise checkout templates (PHP, HTML, CSS, JavaScript) to streamline the step-by-step flow • Tidy up visual details so the design matches the rest of the site • Validate and handle errors gracefully across all checkout steps • Update configuration, virtual hosts, and hard-coded links for the new domain • Test end-to-end on desktop and mobile to confirm a friction-free purchase journey The cart, product pages, and payment gateway are already functional, so no integration work is needed there—just the layout and flow polish. If you are comfortable working without a codebase, can audit what’s on the server, and can turn this final 10 % into a production-ready storefront, I’m ready to get started.
