Leaflet Artwork in Powerpoint - URGENT

Design details: Using existing template / previous artwork, create artwork for a new A4 (4 page) leaflet - exactly the same format as before - from text and logo supplied. There may be a need to add one or two simple diagrams using Powerpoint (but this could be adapted from previous versions). Required by Thursday 12 / 1pm (UK time). We think it should take no more than 2 hours.
Content on the front/back side and body: Front cover with logo and text (original design) then text and diagrams (used from previous).
Ideas for the visual style: Follow previous style
