Smartphone game development (iOS and Android)

Hi all, I am looking for a developer to put together a game that I am making. DO NOT ANSWER IF YOU DON'T TAKE THE TIME TO READ THE JOB POST TO THE END !!! I already have all the graphics element and sound. All the graphic are in vector file and fully layered (EPS files).The developer will just have to put all the pieces together in a very professional way and make it work on different devices available on the market. IMPORTANT: The developer should be skilled enough to make the game fit perfectly all the screen of the different devices working under Android, without deforming or distorting the background element. The Game should be consistent and look perfectly scale on all devices (ios and Android). The game is a very basic shooting game with a moving target, a shooter and the 'bullet'. Few animation on the character (all created in the graphics elements) The game have a full menu, with 3 different game mode. Each mode have the same gameplay, only the goal is different (level mode from 1 to 10 / Marathon Mode / Time Attack Mode) There is a scoreboard recording player's progression, characters to unlock and that is about it. Requirement: - Develop a smartphone game working on iOS (all devices including but not limited iPhone 4, 4s, 5, iPad) and Android Devices (All devices working on Android, including tablet) - The game will have to work flawless and without bugs. - For iOS: Game center - Newsfeed notification implemented in the app allowing him to send push message to users Time frame: The game should be put together between 1 and 2 weeks maximum. Budget: Around 300 USD. I also want someone that think with good judgement, and not only work like a robot! I made the specification as precise as possible, but if something doesn't sounds right to the developer, I rather him/her to tell me about it instead of applying it without thinking. Please I look forward to hearing from you :) !
