PowerPoint Presentation and Templates

We are in need of a graphic designer to work on a PowerPoint presentation. We have an existing rough, 20-slide PowerPoint presentation that needs to be redesigned. The content in the current presentation is in good shape; however we are in need of the following:

*Engaging graphics to accompany the text (includes pictures, graphs, charts, etc);
*Clean, clear layout of slides to help highlight the content on the page;
*Assistance in crafting a visually-winning presentation;
*Suggestions on bulking up or paring down copy

We want a design that is clean, interesting, and clear. An example of the style we are looking for can be found here:

We will be presenting this PowerPoint at a meeting so it needs to be perfect and persuasive. As a result, we are looking at a very fast turnaround time.

**If placing a bid, please provide samples of your work, a list of experience, and your expected turnaround time.**

Please be willing to go back and forth on at least two passes until we feel the presentation is exactly what we need it to be.
