Keynote presentation Design

I have a 16 page keynote (mac) presentation and this needs to be edited to make it look clean and beautiful with some transitions. This has to be done in next 2 to 3 hour as this needs by today. Please note - we don't have a concept for the design yet, but we just put all the content in the pages and you should design it and put contents right place and font, colour, theme etc...
