I run Instagram ads that drive visitors straight to a single product offer and I need a fast, lightweight funnel—built only with HTML, CSS and a little JavaScript—hosted on my existing GoDaddy server (domain, SSL and email are already active). The flow is simple: 1. Page 1 – shoppers pick a product from a small catalogue. 2. Page 2 – they enter shipping and contact details. 3. Page 3 – they pay through Razorpay and see a confirmation. I want to be able to add, remove or update product entries myself at any time, so please structure the catalogue in a plain-text, JSON or CSV file that I can edit without touching the main code. Key deliverables • Responsive HTML/CSS pages for the three steps, plus success/failure screens • Razorpay integration fully tested with both test and live keys • Client-side validation for the form fields and a simple order-summary hand-off to Razorpay • Auto-email (from my GoDaddy mailbox) summarising the order to me and the customer • Deployment to my GoDaddy hosting and a brief walkthrough so I can maintain listings Everything should stay within my INR 2–3 k budget and be ready for traffic as soon as possible.
