Update Powerpoint Slides with consistent theme and fonts

I am in need of a reliable Freelancer to update my Powerpoint slides with a consistent theme and font. The desired outcome of this project is a modern Powerpoint presentation featuring consistent fonts and themes. I do have some previously designed slides that I would like to be utilized, but not all of them. There will also be images provided that should be included in the slides. Experience in Powerpoint design is preferred. If you are looking for an opportunity that combines creativity with attention to detail, then this project is for you!
