Vibrant Colour Trading Game App & Web

I'm looking to create a Colour Trading Game similar to Mantri Mall and Sunwin.

Essential features:
- User registration/login via Phone OTP
- Wallet for:
- Deposit/Withdraw (manual UPI)
- View transaction history
- Colour trading (red/green/violet)
- Admin panel to control game results
- Mobile-responsive website + Android app
- Push notifications

Design should be colorful and vibrant.

Looking for someone on a low budget; ideal for students/learners. Deadline: 7-10 days.
