as3 Classes & Examples

Hi there, I need help writing a few actionscript 3 classes and I was wondering if I could please get some quotes for this. I will need the classes and fla files and well documented so I can learn from them as this is to help me with my studies (yes im a relative nubie). So id like a working example html/swf and fla files so i can see how it all operates and learn from it. //// CLASSES (in order of functionality) 1. class that unload's loaded swf/image/movieclip 2. plays annimation (i.e. circle moving around stage) 3. loader to load next swf/image/movieclip 4. loads new swf onto screen 5. positions swf center stage //// An Alignment Class 1. Pass in a movieclip/image/swf and postion 2. It positions it on stage. //// EXAMPLE It's important I have a working example I can see and look at the code to learn how it operates and works, otherwise there is no point in this exercise for me as im a student learning. The example needs to make use of full browser width and height. All the example file has to be is two buttons that when clicked unload the current swf play annmation (cricle moving) then preloader for next clip/swf then loads to centre stage next swf. If there are better ways of doing this please let me know. I'm open to learning! thank you :)
