Athletic Training & Babysitting Marketplace Apps

I'm in need of a two-sided marketplace with two separate apps - one for the workers (athletic trainers and babysitters) and one for the clients (parents and those seeking training).

Key Features:
- Worker App:
- Schedule management
- Payment tracking
- Profile and ratings

- Client App:
- Search and filter for workers
- Booking system
- In-app messaging

Ideal Skills:
- Mobile app development (iOS and Android)
- Experience with creating marketplace apps
- Knowledge of implementing schedule management and payment tracking features
- Proficient in creating user-friendly interfaces

Your experience in developing similar apps will be a significant advantage. Please include relevant examples in your proposal.
