I want to get an Android app created. The features is that it will have three screens. The first screen should be a login screen with options to log in or create a new account. The second screen will have a few buttons such as Petrol Pump, Hospital, School, etc. The third screen will have a Google Map. A most simple use case can be that if a user visits a hospital or some other point of interest, and wants to save its location, he would press the respective button on the second screen. The app would get the GPS coordinates and save the location in the user's profile on a server. The map screen will be used to see the location on Google Map. The user of this app will be part of a bigger social network, hence the server should be scalable and robust.
Can you give me a time and money quote for this app?
