Editable diagrams to put into Word/PPT (like Sketchbubble)

I have a report to write for a charity about engaging people we haven't managed to reach in the past.
The audience is not going to be specialists so I need to use a lot of pictures (!)

I'd like a range of pre-prepared but editable diagrams to choose from on the subjects.

I subscribe to Template.net and there's nothing on there, but sketchbubble does have the sort of thing I like but I can't afford their subscriptions for a one-off. As much as the design is important, I also like all the information that is currently in their slides so would like that included as far as possible.
