Clone My Already Built React Native Order App and Publish to stores (7 Days)

Its a simple react native / firebase app where people order for certain services (Boats, Trucks, Equipment and Waste Disposal Service) The app have Push Notification and Email Notification for new orders. The app is already completed and tested but system got crashed before we published and we lost the source code hence starting afresh. But the APK file is available. The App has the Users area where orders are made, and the Admin area where admin add new Services / Equipment for the four different categories (Boats, Trucks, Equipment and Waste Disposal Service) and also view orders / users and update Order status and payment status when orders and payments are made. The attached jgb contains some pages just to have an idea of how it is... Will send the apk file which was built which contains all the pages for both user and admin.
