School's presentation Adobe Effect file?

Hello, I'd like to ask that can you suggest me some of your templates (AE) to use? I want to buy one template to use for my school's presentation. I will have some photos, some videos and some text as well. Can you suggest me some templates for me to buy? Also I would like to extend time of pictures and text as well. Because it depends on the number of pictures and texts I will use. Your helps will be highly appreciated. I am also copying a link of a video which was done last year, I am trying to do something alike.
