How much does an Android project cost?

Question

Android

Good afternoon, help estimate the cost of the project:
There is a city game, you need to write a program for it, for Android. The essence of the game: there are crews that ride around the city, completing tasks received on their Android devices, one device is the coordinator (or administrator) of the game itself, the algorithm is as follows: the crew receives the next task, the timer automatically starts, there are two buttons: "done" and "hint". The second button is inactive until the timer ends. By pressing the "Done" button, the crew receives the next task and the new time allotted to complete the received task.
On the game administrator's device, the picture is as follows: there should be a map (google maps, yandex maps) with crew markers, it should be possible to create a new task for a specific crew, at the end of the game a table with results (time spent) should appear, which should be available to players.
More or less like this.
And an additional question, what language (or maybe there is a framework framework) to use to write the game server?

Answer 1

About $10,000 if everything is done on the web, and not with applications for platforms. If applications, then the cost will increase greatly.
A working prototype can be made for $1,500 a week.
Language - any for the web: PHP, Python, Ruby...

Answer 2

icqnavigator (open source
)

Answer 3

Judging by the comment above, I would advise you to look for programmers among the students you know who will do all this for you as a diploma or coursework for a penny.
