Required software development,Website Development freelancer for GPS-based game DEMO app job

Need a demo app.
1. Locate the person's phone on an international map (50 meters radius appears on the map)
2. Suggest to the person to go the nearest building and walk around the inside.
3. at the entrance give the person some points
4. draw the person into the building by placing a points spot 10 meters in
5. ask the person to go to the elevators up and down them and to the other exits and entrances

6. Send the info to the server when they mark the location of the elevator and other things, not through gps but through my friend's app api or if you can show direction around the building 10 meters here and there etc.

I realize gps does not work in buildings.

It is like a treasure hunt
