I’m building a web platform that lets everyday car owners rent out vehicles they aren’t using and allows drivers to book and pay for those cars in a few clicks. The heart of the project is a smooth rental-booking workflow tied to a reliable third-party payment gateway, so users can complete the entire transaction—security deposit, rental fee, extensions, refunds—without ever leaving the site. Key flow I need: • Owners create a profile, set availability and pricing. • Renters search, pick a time slot—hourly, daily or weekly—then pay securely. • Once payment clears, both sides receive confirmations and a shared trip itinerary. I’ll provide the UI wireframes and branding; you turn them into a responsive, production-ready application. Expect typical marketplace essentials—account verification, photo uploads, availability calendar, basic review system (nice-to-have, not mandatory in phase one) and an admin dashboard to resolve disputes and handle payouts. Tech stack is flexible as long as it supports: 1. Secure user auth (e.g., JWT, OAuth). 2. Real-time availability checks to prevent double-bookings. 3. Integration with a mainstream gateway such as Stripe or PayPal. 4. Clean, well-documented code and database schema so future mobile apps can hook straight in. Deliverables • Full source code in a Git repo. • SQL/NOSQL scripts for initial data. • Read-me with setup instructions plus a short deployment video or screenshots. • Post-launch support for bug fixes during the first month. If you have built sharing-economy or booking systems before, let me see them—speed to market matters.
