Canva or Powerpoint slide deck

I need a 12-14 slide deck producing, from copy I will supply, to a relatively simple Corporate format (typeface, colour example and logo I will supply) explaining a proposition to a client. Some simple illustrative graphics and added colour is required to enhance the message. I am not looking for anything complicated and don't want stock cartoon-llike icons for the illustrations. Needs to be turned around quickly.
