I need a Powerpoint designer with bar chart experience

Have 60 bar charts need done tomorrow, then reduced adn stacked 3 to a page. I'll have all data pulled tonight and ready to hand over. Don't think it will be hard, just tedious but a two part-ask: (1) Put data into bar charts and then (2) Reduce them and stack them 3/page in a powerpoint template deck I'm using so they're aligned and can be compared by stacking one on top of another.
