Startup Idea: Beauty Salon Scheduling and Advertisement App

Startup idea to develop a mobile application for both Android and iOS that enables users to schedule salon appointments, view ratings and service information, find nearby salons, and receive special offers from salons within their network. The app also offers advertising services to salon providers.

I am trying to develop an app for android and ios that would do scheduling between beauty salons and customers. For example, if somebody was in a hurry and was far from their usual place, then they would use the app to locate a spa near to them. The app would include rating and services provided be each salon close to them. Additionally you could charge each provider or beauty saloon for them to advertise in their app and be able to offer discounts and new products and services to clients in the network.
