I have a Powerpoint presentation of approx. 150 slides. I have written it and it looks good, with consistent fonts etc but looks dated compared to today's styles. I'd like the presentation to have a wow factor as it is being presented to an audience, (i.e. like it was made from a design / marketing department of a large company). There are some slides with pictures of slides taken from elsewhere which I'd like re-done as they have different styles. The aim is to have a consistent design language across all 150 slides. Right now it looks like a patchwork of styles.
I'm open to pictures being changed as well as layout / theme changes, however I do not need any content written. I have a logo I have copied, it would be a bonus if I could get a fresh logo that better represents my business for the presentation.
I will mark which slides I'd like re-done from scratch as well as identify the font and sizing I'd ideally like across the document.
