Android and iOS App development

Developing a saloon/barber app (android/ios), that will enable clients to request an on-demand barber/stylist to come and perform their services at the clients' location. The app will need to enable payment through the app to ensure a guarantee of service and payment for both client and barber/stylist, as well as location services to identify service providers nearby and their journey when in route, and a database to store all app info.
