Vibrant Stock Simulator App Development

I'm looking for an engaging, colorful and vibrant stock simulator app to be developed for both Android and iOS. The app should facilitate stock market learning for school students in a fun and interactive way.

Key Features:
- User Groups: The app should allow students to select their school group during the signup or login process.
- Introductory Video: Upon logging in, users should go through a video splash.
- Practice Coins: Every new user should receive 1000 'infictuas coins' for practice.
- Company Creation: Students should have the ability to create their own companies.
- Trading: Users will buy and sell stocks.
- Banking Functionality: There should be a banking page where students can apply for loans, subject to admin approval.
- Multiple Pages: The app will include a Dashboard, Market, Study, Portfolio, Company, Banking, and Leaderboard.
- Admin Page: An admin interface is necessary to manage users and approve loans.

Ideal Skills:
- Cross-platform app development (Android and iOS)
- UI/UX design (colorful and vibrant)
- Firebase for backend management

Experience:
- Prior development of educational or simulation apps would be a plus.
- Experience with creating interactive and engaging UIs.
- Strong understanding of Firebase and its implementation in app development.
