I have to do these all the time, they’re actually quite a challenge – when was the last time you enjoyed a PP presentation?
Hint hint…..

Watch a few, get some ideas. The ultimate in boring is slides with loads of text on "That. You. Read. Out. What. Is. The. Point. Of. Reading. What. Your. Slides. Have. On. Them. While. Your. Audiance. Reads. The. Same. Thing. At. A. Different. Rate?"
And will you remember 2000 words on PP slides when the person is expressing themselves in a different way at the front?
Nah.
Images on slides, maybe a heading or two if you must. Talk with enthusiasm and keep it punchy.
I’d also suggest sourcing high res images [1900 wide and scale down] and skip those fancy transitions.
That’s my input, anyway.
