Revise a Presentation Deck

Someone needed to revise a presentation deck that was created in Canva. The deck has 5-6 slides and will be used to inform potential speakers about an event and ways that they can be a part of it. The presentation deck has most of the copy that will be used and a website link will be provided that has full details. We need the presentation deck to be very eye catching, dynamic and fit the look and feel of our vision.
