PowerPoint Design Process Flow for Rare Disease Patient Registries

This is what a business in United States was looking for in their PowerPoint design

I have attached a powerpoint presentation I need professional design on. This describes our CONNECT program and the current process and screenshots are include in the attached file. We would like to keep the process, flow, screenshots and images but need it designed to be more visually appealing while stepping through the process.

Looking for a visual queue that let's the user know what step in the process we are on as we then describe the details of that step. We want to reinforce the 5 steps in the process and keep that on each slide. Suggestions on the initial page where we introduce the process before going into the details.

I have attached an image of a button that we will be using for registration buttons and if you could reflect that kind of shape or look and feel that would be cool. Please check http://www.patientcrossroads.com to see our colors.
