Enhance Powerpoint Slide Presentation

I have a slide presentation deck which has a clear design but I need to update it for a new audience so the new slides I add will not fit with the existing style and layout. I need someone to help to edit the new slides to check that they fit with the existing design, improve the new slides where needed (i.e. some may need infographics, headings, alignment), and ensure that the overall deck looks consistent and is easy to present.

It is for a training session I'm delivering early next week, but I would like the first round of edits done in the next 24h (by 2pm UK time Thursday 29th) and then I can give comments so that the final version can be made on Friday 1st or very latest Monday 4th (UK time).

Am working on this now so unsure the exact number of new slides (estimate 10-15), but interested to receive quotes for someone who can work on this within the timeframe. The deck with suggested edits will be ready soon to share with people to estimate the number of hours needed. No need to make lots of additional edits the deck just needs to look clean and function smoothly.

Interested in quotes from people who can engage with the exact brief for the project. Thank you.
