I need some help making Google slides look good

I'm writing the content for a presentation but I need it to look good with images, logos and the right font and formatting. There will be 5-8 slides in total, they don't need to be amazing graphically, it just needs to be presentatable, clear and engaging. Please note I'm in meetings most of today so probably won't be looking at proposals until Jan 6th but I need the slides ready by Jan 7th 5pm UK time.
