Graphic Image or animation for a powerpoint slide

I have some art pieces in a photoshop file. I need to use these pieces and perhaps other from outside to create a graphic image for a powerpoint slide depicting information flow/ business workflow. This graphic will need an iphone & ipad image which I don't have - so I would be looking for the free-lancer to provide that. Although, I will be happy with one image that can be used on a powerpoint slide, if some powerpoint expert can suggest another way to animate the image to have a better impact that would be even better. Please submit samples of a business process diagram, workflow diagrams or a powerpoint you may have developed. Max Budget $30.
