need a tiny piece of xml code writing

I have a card flip game which needs two things added... 1. the end movie needs aligning to center of the stage (for some reason it is way off centre when you open the game in full screen window. 2. When a card is pressed a sound (particular to that card must sound) This needs to happen inside the xml script and be easily customizable, as I need to make many versions of this game. I wlll pay $30 for project. thanks Stephen
