Presentation to be updated

I need someone with experience to update my presentation to ensure that it flows and looks professional, I have created the presentation on Canva and require someone with a good eye who can refine the look so the presentation represents a luxury brand. The content is already there which needs to changing and is just the aesthetics and design that would need altering.

The presentation stands at 27 slides and if you are the right person then I have an additional 5 presentations that would need to follow the same style and remain consistent as a "global presentation"

Please send me examples of what you have already produced. Please bear in mind I DO NOT WANT ANY GENERIC TEMPLATE DESIGNS.
