Hi, I'm looking for some help with creating an iPhone / Android Game that involves physics (angrybirds real life physics) and I need someone to program my game for both iPhone and Android platforms

I currently design my own games, so I will only need someone who can write the program using my images I created.

The game design is completed, I only need someone to program the game for iPhone & Android.

I'm looking for help creating a slingshot (Angry Birds) , where the user pulls the slingshot back with finger , then releases it and the object will fly into the direction the user was pulling.

Again, I'm only looking for serious bidders only, with experience in iPhone or Android Game app development.

I will only hire programmers with a portfolio or previous app experience
