Mobile Marketplace App Development

I need a complete mobile marketplace built from the ground up that lets users list, browse and purchase physical products—specifically electronics, clothing and home goods. Offer services such as hair cuts and more. The core flow should feel as seamless as the big-name shopping apps: quick onboarding, clear product cards, robust search and filtering, a straightforward cart and a secure checkout.

On the seller side, I expect profile creation, inventory controls, order management and basic analytics. Buyers need order history, An admin console must give me the usual levers—user management, dispute handling, category edits - without extra engineering work every time something changes.

Key technical essentials I’m counting on include:
• Native iOS and Android builds (or a high-performance cross-platform stack you’re confident will scale)
• Payment transaction will only be for subscription, purchasing payment will be between buyer and seller
• Image compression and caching so high-resolution product photos don’t slow the experience
• A modular architecture that’s easy to extend to services or digital goods later
• ID Verification when users sign up for the app
• Monthly subscription or 6 month subscription
• Random usernames to be created for each profile made
• 6 month use for profile. After 6 months profile will automatically terminate for all users
• messages between users can be made on app

Deliverables I’d like spelled out:
1. Interactive prototype for sign-off before you dive into full development
2. Production-ready mobile apps, source code and documentation
3. Admin web panel with deployment scripts
4. Post-launch support window for bug fixes and app-store submission guidance

If you’ve delivered a marketplace at comparable scale, show me links or store listings so I can check the UX. Let’s discuss milestones and timelines as soon as you’ve reviewed these requirements.
