Game Developed with Backend for Scoring Points and Redeeming Prizes

Please read the entire description as well as the attachment. When I get "blasted" from resources that have a "canned" response it tells me that you didn't take the time to read the requirement, thus not sure if you even have the experience. We currently have a backend developer but if you have the resources to also design the backend as well as the client then we would consider working with you for both the client and the backend. Here's the requirement: Seeking a developer who can build a 3D Game which will be integrated with a backend and be able to build a lavish, and lucrative game, with social API’s integrated, with scoring, rankings and achievements which will be uploaded to our server. The player will accumulate points by playing the game. They would need to purchase coins as an in-app purchase according to Apple guidelines, but would visit our site to redeem their points for prizes which will be shipped to their door. Could be a 3D strategic coin pusher game. User will have some coins and can push on stack of others to earn. They will have a limited time for pushing them. Player will have certain amount of coins at the beginning, (amount that they have paid for through our server) and he would be able push coins on top of machine and coins lying underneath would move and will fall off from the tray (if there would not have enough room) the more user pushes coins, the more chances he will have to fall the coins off the tray. The coins that falls off the tray would be added to users points. User will have a limited amount of time to play the assembly, once the time is over user would be able to submit the score as the number of coins that he have left with at the end or buy more credits. See this arcade game for a great example. If you can do this on the iOS and Android, that would be great. [login to view URL] See attachment for more information. Thank you.
