Advanced Scroller

[login to view URL] This framed website was created using a scrolling layer and a very wide jpeg image. The image has been mapped so by clicking on certain parts of the image a page (or pages) of text appear in the lower frame. I want to improve this so there is an option that the details in the lower frame will change when the relevant mapped area is passing the mid point of the frame. I want to improve the speed control with a normal and a jog feature. I also want the ability to add mp3 files. And to be able vary the size of the jpg image to a % of screen size, and to print the part of the image currently on the screen. I am a web designer and am looking for a programmer to write to Flash or JavaScript for this project.
