Business Consultation Video App

I’m launching a dedicated business-to-client consultation app and need an experienced developer to take it from concept to store-ready release. The core experience is a smooth, high-quality video call that lets consultants meet face-to-face with their clients, so familiarity with WebRTC, Twilio, Agora, or equivalent SDKs will be essential.

Alongside the live video, the app must include:

• Scheduling system – clients browse available slots, book, reschedule, and receive push or email reminders.
• Payment integration – secure in-app payments before a session starts, using Stripe, PayPal, or another PCI-compliant gateway.
• Chat functionality – text, file, or image exchange before, during, and after calls.

All users sign up with email and password; role-based access will separate consultants from clients. I’ll provide wireframes and branding assets, but I’m looking for you to handle the full build: database schema, API layer, mobile front-end (React Native or Flutter preferred), basic admin dashboard, and deployment to App Store and Google Play.

Please outline your proposed tech stack, milestones, and any previous work with real-time video or scheduling platforms. A short timeline and clear testing plan will help me decide quickly.
