Simple 2D physics based flash project

I need someone to make a specific flash project. It will act as basis for a game but does not require you to make it ready as a game (just an example test level, no balancing, no content design needed). I will provide the chosen maker a brief and clear (about 5 pages, mostly pictures) design document for the project. Basically it is like an extended pool table. A level consists of 2D balls and boxes inside a 800x600 pixel flash area (the "pool table"). There is no scrolling. In the beginning of the level, the player/user can give speed vectors to all balls (click with mouse and drag the vector, initial locations given in source code). He can then press a 'RUN!'- button in a menu bar in the bottom of the flash area and the physics simulation runs until all balls and boxes are at rest. There is a certain success criteria for the end state to pass or fail the level. I'm a c++ games programmer who wishes to learn flash with the little free time I have left. It is important that you integrate some free flash 2D physics engine to handle the physics simulation and provide me the whole project and source code with brief but good code commenting so I can continue and play around from there on. My tool is Adobe Flash CS3 professional.
