Box2d physics game

We are creating a flash game that mimics Angry Birds. Projectiles will be launched from a slingshot and will hit a structure, which will cause it to partially collapse. You get 3 chances to free the animals trapped inside the structure and will be rewarded points for how well you do. Depending on your points total you will get one, two, or three stars (if you are successful). There will be 10 levels, all featuring a different structure -- but made with the same components. The projectile will always be the same (ie: like using the standard "red bird" in Angry Birds). We will provide all art (including backgrounds)as well as sounds and project management; we ONLY require programming. We are an experienced game company and if this game is done well and completed on time there will be follow-on projects (additional levels, porting to iOS). This is who we are: [login to view URL] A game design document is attached for full details. Please do not bid if you do not have flash game programming experience. Box2D experience is also required. Thank you.
