Game for android required

I am starting a project where i need a game made for android, i will also require iphone version, now the game needs good graphics im not looking for a 3D/ high def graphic designer but someone who can create me simple looking things, for instant the app cut the rope and angry birds. My game is being a monkey, you have to go through these mini quest, for instant at world 1 (map 1) you sling the monkey, like angry birds so it breaks through certain things like boxes, crates to gain a monkey statue, there are 5 ground before we get to the game room, each ground has certain amount of statues and a time limit of like 5-30 seconds, collect as many you can each statue gives 5 seconds in the game room, once all 5 grounds done, you will deposit all statue and claim the amount of time you have in the game room, once in the ttime sets off and you have to answer questions, solve puzzles, and get the golden statue which has points inside, which with that you may upgrade your money with jet packs and other goodies. If you have seen a tv show for kids called jungle run it is very simillar concept. Im looking for a developer, understand and speaks clear formal english, fast and supportive. I will require graphic, and sounds which will be discussed further once we have an agreement.
