Clear and focused PowerPoint for a CEO / CFO pitch - freelancer

I have a number of slides which have too many words, and I am confusing the message about what services I sell

They need to be sharpened up to show the following

- elevator pitch
- what problems do I solve for CFO/CEOs
- the services offered
- why do projects like the ones I do fail and why I always deliver
- how do I add value that other consultants don’t
- 2 case studies - brief, direct and to the point
- what services do I offer... I do some initial work around workplace psychology, understanding people and how they work in office spaces, then the client decides what steps they want to take next be that construction and refurbishment, facilities restructure, organisation restructure, process changes and enhancements

It needs to be clean, crisp, clear, pitched to a CEO, and a professional .. currently it looks like a child produced it
