AS3 Flash Video Load/Unload

I need a simple Flash file containing the following parameters: AS3 3 Movieclips on stage that when pressed load external swfs. The swfs need to alpha tween in and out when loaded and unloaded. The swfs will need to be able to contain video but be totally unloaded and garbage collected when removed from stage. Don't need any graphics just the 3 movieclips and actionscript on one frame of the timeline. Once code is tested payment will be transferred. Thanks
