Easy Universal Game for iPhone

Budget $1300 Max. A developer was working on it and failed, hence the need to hire another developer. I want to port a very old game (which was played on the old Spectrum and Atari 20 years ago) to the iPhone. I want to make it a universal game for iPhone/iPad/iPod. The game was called Highway Encounter. I want it renamed to Vorton. Of course, this new version will be made for the 21st century with the best graphics and multiple levels. It will be made in a similar style with similar graphics to what all top games do nowadays. It will have a tutorial, sounds, hints, options etc… I don't like music but I want plenty of sounds. Before even beginning to code this game, you need to keep the mindset that this is due to become the No.1 game. You must therefore make it look and feel like a number one game with no shortcuts in code. All code must be commented as usual practice. I also want to make extra levels available through in-app purchases. The game itself is very simple and simple to program due to limited functionality. Therefore, the cost will be low. The iPhone version will have a little more functionality and more objects, to cater for the new style of updated games. I need for the game to be extremely enjoyable and playable like: Angry Birds, Cover Orange, Chicks, Cut the Rope etc… All these games reached near the top because they were multi-level games. When the user finishes a level, he returns to the "level" screen which shows that he can now proceed to the next level and that unlocks. I would like 20 levels for this game (to start with). Along with the game, you need to provide all the relevant graphics, icons etc... ready for submission to Apple. The controls in this game involve a joystick and a fire button. Joystick on left and Fire button on the right-hand side of the screen. The location can be switched within the options. The joysticks can be invisible but can be utilised by placing thumb on any part of the left side of screen. It has to be a good joysticks which takes into account acceleration and also turning without movement. To learn how this game plays, you need to watch 2-3 Youtube videos. Then it will be easier for you to understand and easier for me to explain. First watch this video.
