Power Piont Illustrator

I am in the process of finalising a power point presentation (currently 24 slide long), and am looking for some one with the knowledge to be able to take my draft lift the presentation from the norm to one that looks professionally produced by including a number of bespoke illustrations/drawing.

If you think you can help I am trying to finalise this over the weekend/Monday.

The attached the first draft (the text is very rough at the moment so please excuse this) together with sketches of what I require beautifying.

Thanks
