Hourly Home Cleaning Booking App

I’m ready to build a mobile app that lets homeowners hire a cleaner by the hour, whenever they need one. The app must run seamlessly on both iOS and Android, and I’m open to either a shared code-base (Flutter, React Native, etc.) or separate native builds if that proves better for performance... (Budget: $2 - $8 USD, Jobs: Android, Flutter, iOS, iPhone, Mobile App Development, Payment Gateway Integration, PHP, React Native)
