I need a straightforward reverse-auction website dedicated to Recreational Vehicle transport across the United States. Shippers will post a haul request, transport providers will place and track bids in real time, and once the auction closes the lowest active bid wins automatically. No funds move through the site—customers pay their carriers directly when the job is finished, so the workflow ends with an invoice rather than an online checkout. Three user roles must be fully supported: • Service seekers who create and manage their listings • Transport providers who search listings, submit bids, and receive job details • Administrators who oversee user accounts, monitor auctions, and resolve disputes All critical alerts—new bid, out-bid, auction won/lost—should reach users via SMS. The interface can still show notifications, but text message delivery is mandatory. Deliverables 1. Responsive web application (desktop & mobile) covering the functions described above 2. Secure sign-up/login for each role, including basic profile and rating display 3. Bid dashboard that updates automatically without page reloads 4. Admin panel with full CRUD control over users, listings, and auctions 5. Deployment to a live domain with SSL and basic performance tuning 6. Documentation: setup instructions, user guide Acceptance criteria • A test auction can be created, bid on from a second account, and closed with the system declaring the correct winner. • Both parties receive SMS messages for every status change. • An administrator can revoke a user and the account disappears from public views immediately. If you have built auction or freight-matching platforms before, please mention the stack you used and link to any live examples.
