Need a Javascript app to scroll DIVs and integrate to page

Hello, We basically want you to develop for us a Javascript applet which looks and works EXACTLY like the one you see on the front page of: [login to view URL] So when you click the Arrows, a DIV will move up or down, just like there site with that slow easing towards the end of the movement. Inside the moving div, we will have Flash Objects as well as Images (each div will be different). Once developed, we will need you to modify our [login to view URL] to add the code so again, the final result is exactly like the one working at [login to view URL] with our Flash components and Images scrolling inside those DIVs. Sean.
