Wholestone Powerpoint Template

I'm in need of a Powerpoint expert that is well-educated in best practices. I have a template already created, but it doesn't function the way my client would like. I need the formatting and transferring of slides to be easy. Right now, you never know what you're going to get when you copy over content. Maybe it's just the nature of Powerpoint? If not, I would love to have someone get a proper template assembled.
