Presentation for Executives

I have 4 power point slides that I would like to have designed to be engaging to the executives I need to present to. These are all former CEOs of large, multi-national companies with revenue of +$20B. The slides include and executive summary, conclusions, findings and remediations. There are two options for content for the executive summary, conclusions and findings. I have a few different options of design/context available and would like to have options created to ensure the material is engaging. I would like a blue or combination of blue, purple. green theme.
