Make a tennis 3d game for Android and IOS( iphone and Ipad)

Hi, I want to make a 3d tennis game like 3d Tennis for Android and IOS( iphone & Ipad). The url is below [login to view URL] The physics of the game must be very real. The game must serve ads from multiple ad networks to try to fulfill 100% fill rate. I prefer to use Appodeal for ads. The code must be obscufated using software like Proguard. Please let me know your best price, time frame, game development software that will be used to make the game. I will hold all the copyrights of the game. There must be no reskining of my game. Thanks Vishal Ved
