TONIGHT - tidying up a presentation of about 30 slides

I have a powerpoint / google slides presentation, which I need tidying up to make it look more presentable / excellent.

It is being finished as we speak (in around 3 hours time) and I need to have it improved by tomorrow morning UK time (so literally a 6 hour turnaround.

I don't want too much time spent on it, but looking for someone who can spend about 4 / 5 hours on it tonight to improve it and make it look more shiny

Please give me 5 examples of presentations / investment decks you have done to show me what sort of thing you can achieve and within this timeframe..

Thanks!
