Flash actionscripters needed quite urgently

We are looking for a flash actionscripter to write some functions for a Flash presentation we are doing. First one: We want a function which when a key is pressed, it will fade out the music, and fade the visuals to black. Timing to be set as a variable. This needs to be as easy as possible to drop into our fullscreen presentations. Also with this need to be able to mute/unmute all sounds by pressing a keyboard key. Please bid for this first function, there is likely to be more work after this. Bidder must be familiar with music use and control as we have some queries relating to music files we are using. Mockups/demos will help a lot in choosing a bidder. Ideally the bidder will be available on MSN after they are chosen. Thanks
