Full-Stack Developer Needed for Fixed-Scope Marketplace Web App MVP

Project Overview I am the founder of MoveSpeedia, an early-stage moving marketplace. I am looking for an experienced full-stack developer to build a lean, responsive web application MVP that allows customers to create a moving inventory, receive pricing, compare available moving carriers, and book a move online. This is a fixed-scope validation MVP, not the full long-term product. I am intentionally keeping features lean and am willing to handle some operational processes manually behind the scenes during the MVP stage. I already have the business concept, customer flow, pricing logic, and prototype/design direction established. Core MVP Goal A customer should be able to: Create inventory → receive pricing → view available carriers → select a carrier → book/pay → receive confirmation Carriers should have a simple portal to manage the information necessary for them to appear as an available option. An admin dashboard should allow me to manage the marketplace manually when needed. CUSTOMER-SIDE FEATURES 1. Customer Move Intake Pickup location Destination Move date Basic move/contact information 2. Inventory Creation Customer selects/adds household items and quantities Inventory produces an estimated cubic-foot total Ability to make changes before booking Photo upload capability is preferred if achievable within budget Advanced AI/computer-vision inventory recognition is NOT required for this MVP 3. Cubic Feet / Weight Conversion This is important because the initial market is Los Angeles/California. The system should: Calculate estimated cubic feet from inventory Convert cubic feet to an estimated weight using an admin-configurable conversion factor Preserve the cubic-foot inventory internally while allowing pricing/estimates to comply with applicable weight-based requirements The conversion formula/value must be editable through the admin dashboard rather than hard-coded. 4. Carrier Comparison Display eligible carriers with basic information such as: Carrier/company name Price Basic service information Available pickup window/date Simple comparison/selection interface This does NOT need sophisticated automated dispatching or route optimization for the MVP. 5. Booking Customer selects a carrier and confirms the move. 6. Three-Payment Flow The MVP needs to support the planned three-stage customer payment structure. Exact amounts/percentages should be configurable rather than permanently hard-coded. Stripe is preferred. The developer should propose the simplest reliable way to implement this within the MVP budget. CARRIER PORTAL Carriers need a simple login/dashboard where they can maintain basic information including: Company/profile information Service area/routes Availability Basic pricing Capacity/availability information needed for marketplace matching This should remain intentionally simple for MVP. I am comfortable manually assisting with carrier onboarding. ADMIN DASHBOARD — IMPORTANT I need an admin dashboard that gives me flexibility to operate the MVP without needing a developer every time something changes. Admin should be able to: View customers View bookings View carriers Add/edit/deactivate carriers Edit carrier pricing Edit pricing assumptions/rules Edit cubic-foot-to-weight conversion value Adjust a customer's inventory if necessary Adjust booking pricing when a legitimate change is required View payment/booking status Manage basic marketplace information For example, if a customer accidentally leaves out a bedroom or inventory needs to be corrected, I need the ability to update the booking rather than having the application become unusable. ENGLISH + SPANISH The MVP must support both English and Spanish. This is important because the initial target market is Los Angeles. I do NOT need a complicated translation management system. A simple bilingual implementation is acceptable as long as customers can clearly switch between English and Spanish and the major customer-facing flow is available in both languages. I can provide/review final Spanish copy if needed. RESPONSIVE WEB APPLICATION This is a web application, not a native iOS/Android app. It must work properly on: Mobile phones Tablets Desktop Mobile usability is especially important. DESIGN I already have prototype/design work that can be provided to the selected developer. The MVP does not need excessive animation or custom visual effects. Priority is: Clean + trustworthy + easy to use + functional TECH STACK I am open to recommendations. React / Next.js or another modern web application framework is acceptable. I care more about: Reliability Maintainability Clean code Ability for another developer to work on it later Keeping infrastructure costs reasonable Please explain what stack you recommend and why. DEPLOYMENT / OWNERSHIP The completed application should be deployed to my domain or an appropriate MoveSpeedia subdomain. I must receive: Full source code Repository ownership/access Database/admin access Hosting/deployment access API/payment account configuration under accounts I control Basic documentation necessary for another developer to maintain the application All code and completed work produced for the project must belong to MoveSpeedia upon payment. WHAT IS NOT REQUIRED To keep the MVP within budget, I am specifically NOT requesting: Native mobile apps Advanced AI/computer vision Automated room scanning Complex route optimization Advanced analytics Complex carrier dispatch software Fully automated operations Large-scale enterprise architecture Those can come later if the MVP validates the marketplace. BUDGET & TIMELINE Fixed project budget: approximately $3,000 USD Target timeline: approximately 4–8 weeks, although I am open to a developer's realistic recommendation. I prefer milestone-based payments tied to working deliverables. WHO I AM LOOKING FOR Ideal developer has experience with some combination of: Full-stack web applications Marketplaces Booking platforms Stripe/payment integrations Customer/admin dashboards Responsive/mobile-first applications Multilingual applications React / Next.js or similar frameworks Developers worldwide are welcome. Clear English communication and dependable communication throughout the project are important. WHEN APPLYING, PLEASE INCLUDE Please answer the following instead of sending only a generic proposal: 1. Have you built a marketplace, booking platform, or similar web application before? Please provide examples. 2. What technology stack would you use for this project and why? 3. Can you complete the described MVP within approximately $3,000? If not, identify specifically which feature(s) create the issue rather than simply providing a higher total price. 4. What timeline would you estimate? 5. How would you structure the project into milestones? 6. Have you implemented Stripe payments before? 7. Have you built multilingual applications before? 8. Are you personally completing the development, or will the work be outsourced to another developer/team? I am looking for someone who understands the purpose of an MVP: build the smallest reliable product that lets us put real customers and carriers through the marketplace and validate the business.
