Develop a Mobile Game

I need to have a Mobile Game identical in Design Logic, Physics, Animations and Features and similar to “Subway Surfers” mobile game in which the Avatar is ‘running’, ‘jumping’, ‘sliding’, and ‘surfing’, and collects ‘items’ (instead of coins) on a path. The game will require some customization/modifications in the Graphics, Background & Colors and Character, and Sounds/Audio. Bi-Lingual (English/Arabic) will be included in the Interface and Audio. In addition, I need the game to include some advertising banners inside the game in the Background while the Avatar is running. The purpose of the game is to advertise some products (which will be included as graphics items and banners inside the game). The Game should be Multi-platform to run on iPhone, iPad and Android and (optionally) Windows phone. Also the Game should be developed in Unity3D. A Complete Source Code ‘Tested and Bug-Free’ is needed to be provided with the game with 1 year support service. (Note: If this project is a success story, I will have more requirements for more games). I am a Web-developer and I have a client of mine that have requirements for a game to advertise his product, and he allocated limited budget for this project. Please note that, I will provide you with the materials of Images and sound files of (Graphics, Background, Character Design and Audio materials) as I do graphics design, so you do not have to worry about Graphics issues.
