Astrology Consultation App Build

Hi,
I am looking for a skilled mobile app developer (Flutter / React Native preferred) to build a basic astrology app MVP. The app should allow users to connect with astrologers via live audio calls and chat, with a per-minute billing system, and also include a 1-minute free auto chat feature for new users.
App Requirements (MVP):
User Side:
Signup/Login (Phone, Email, Social Login)
Browse astrologers by expertise, rating, language
View astrologer profiles
Book instant audio calls or chat with astrologers
Wallet system for payments
Per-minute billing for live audio calls
1-minute free chat automatically for new users to attract them
Call/chat history
Rate & review astrologers
Astrologer Side:
Signup/Login with admin verification
Set availability and per-minute rate
Accept/reject incoming calls
Earnings dashboard & payout request
Admin Side:
Approve/reject astrologer profiles
Track transactions & call logs
Handle disputes/refunds
Technical Requirements:
Cross-platform mobile app (Flutter / React Native)
Backend: Node.js / Django / Laravel
Database: MySQL / PostgreSQL / MongoDB
Payment gateway: Stripe / Razorpay / PayPal
Live audio call integration: Twilio / Agora
1-minute free auto chat functionality
Hosting: AWS / DigitalOcean
Deliverables:
Fully functional MVP app (audio call + chat + 1-minute free chat + per-minute billing)
Source code & documentation
Optional / Future Enhancements:
Video calls, AI-based predictions, notifications, subscription plans
Notes:
Video call NOT required for this MVP to keep costs lower.
Detailed blueprint/flowchart available to share with selected developers.
Please share your portfolio / past apps and an estimated timeline & cost for the MVP.
Looking forward to working with a serious developer!
