Development of mobile application

Good afternoon,

We are looking for capable and creative mobile app developers to build our own.
We are talking about an application with geolocalization in a real connection.

We have an idea of the desired application, its possible design, but we need to design this into reality.
To estimate the cost and timing of our project, you can rely on the existing similar application UBER and its site, but in a very lightweight form and with little traffic to start with.

Our project: an application with clearly separated 2 types of services and with real geolocation for one of them, it must be linked to the site: for service providers and users of the application.

I would like to know the detailed tariff and terms: minimum and maximum? Your comments, if any.

Thank you in advance,
natalia
