Mobile Android game, Trajectory based game with friends.

I am currently trying to determine the actual full cost of developing this game fully functioning so my range is large. I want to have bids on making from start to finish. An android app game. This game would have only about 5 different screens with not a ton of graphics. It would be using the camera, trajectories from a slingshot kind of like an artillery game, and also use Google maps with gps for sensing your and your friends locations. It would also have wind shifting to make it harder after shots. Has a shooting screen with an animation while using a still shot from the camera, then shifting to an animation while using the google map screen. It has a screen with a small animation to build a barrier of logs, and also an animation if it gets hit, your log breaking apart. Then has a screen with a tree that you can touch choices to get prizes like extra logs for building or ammo or a bad prize that has an animation of something eating all the other prize choices so you cant choose anymore. It is a game that is like words with friends in the way that it works by playing back and fourth. You need to be able to find friends from Facebook and invite them easily to play. You can also post wins to your facebook easily with a click. I have screen shots available of my ideas once I choose a programmer, but you will have to do all design work, building and animations and all other graphics. I will have some sounds to put in as well. I need all graphics made custom with sounds. I want real bids from someone that wants to start building.
