Korean iOS/Android Service Marketplace

I need a complete mobile marketplace built for both Android and iOS where professionals can list and sell their services. The backend will run in PHP and must include a Korean payment-gateway integration so users can pay, get paid, and track transactions natively in KRW.

Core flow
• Professionals create an account, write a service description, set a price, upload photos or documents, then publish the listing.
• Customers browse or search, view profiles, and pay securely through the integrated gateway.
• After each job is completed, both sides can rate and review one another.

Although the primary focus is “professional services,” the platform should remain flexible enough to host anything from healthcare advice to legal or consulting work, so the data model and UI cannot be hard-wired to a single industry.

Tech stack & features
– Native or hybrid apps for Android and iOS (state which you prefer).
– PHP backend (Laravel or similar) with REST/GraphQL endpoints.
– Korean payment-gateway SDK wired to both apps and server for receipts and payouts.
– Push notifications, basic chat, profile management, review/rating module, and an admin web panel for moderation, analytics, and refund handling.

Acceptance criteria
1. Android APK and iOS TestFlight build pass store review checklists.
2. All payment flows (card, escrow release, refund) succeed in a sandbox and live environment.
3. Service posting, search, booking, and review cycles are fully functional and persist to the database.
4. Source code and install scripts are delivered in a Git repository with clear README.

If certain parts—such as UI design or server deployment—need to be split into milestones, let me know how you would stage them so we can keep the rollout smooth.
