Modify Existing Unity VR Game and Publish for Android & iOS

I am looking for Unity developer - preferably with experience developing games for Android/iOS - to finalize a game and make it work as a VR game for Android and iOS platforms. The core task is to remove the keypad and mouse controls for the game and use the motion sensors in the mobile phone instead. The game The game is like Smash Hit, the Android game. Deadline: 01/11/2016 The Specification Overview:- 1.) The game is already developed. Currently the user must use the mouse to look around and the keypad to move up/down/left/right. I want the user to be able to move their head to look around and also to navigate the game world, all within their VR headset, without having to touch the screen or use a controller. 2.) I need somebody to add more length to the game, just like how Smash Hit has a continuous and long game world, with new levels that appear consecutively, without a menu popping up. Currently, only level one has been completed. I would like the game world to be extended by 4 times and for the sky and game objects to change when the user reaches the end of stage 1, then change again after the user reaches the end of stage 2 and so on... 3.) After stage 1, the user must pay to continue playing the other levels. I would like you to enable in-app billing for each platform at this stage. 4.) I would also like a menu requesting the user's name and e-mail address on the very first occasion that the load the game. If the user has entered the email and name, then they will never be presented with this form again. As the game is already completed and this is just an extension of an existing platform, with some additional asset generation required, I am looking for someone who has excellent graphic design skills in a 3D software package and who can also modify the C# code to enable the game to work without the user having to touch the screen/use a controller. If the game becomes popular as a result of our marketing efforts, we would like to rehire to repeatedly make modifications and help design future levels. I look forward to receiving proposals.
