I need a full-featured export website that showcases mixed goods—from rice to bike parts—and lets visitors arrange international deliveries in one seamless flow. Core requirements • A clean catalogue where I can regularly add or remove products across multiple categories. • A real-time price-checking module that combines weight-based pricing, destination country selection, and a package-dimensions calculator. Results should pull the latest India Post tariffs (their API or any other reliable method you recommend). • End-to-end parcel booking: customers must be able to either schedule a pickup at their door or choose a drop-off location before checkout. Once booked, they should automatically receive the India Post tracking number. • Responsive design, secure payments, and an admin panel simple enough for routine edits without coding. I’m flexible on the tech stack as long as it integrates smoothly with India Post and scales for new products later. If you’ve built shipping calculators or handled postal APIs before, please tell me how you’d tackle the integration and an estimated timeline for dependable delivery.
