Animated barcharts in PowerPoint

We would like to have animated bargraphics in PowerPoint. When you have a look at the page [login to view URL] you will see the bargraphtype/style that we would like to add. It goes both about the style (same graphic) as well as the animation. On this example page the animation is only shown when the page is loaded (reload the page to see it again), but in the PPT we would like to see the animation as a mouse-over effect. Finally the values and labels must be adaptable in a way. Perhaps a flash job? Do you see solutions to develop than place your bid. Bids proving you expertise by menase of examples will be considered first. Budget is an idea when not sufficient feel free to bid above $. 250,- however resources are not unlimited.
