'Sprucing up' of short (12 slide) powerpoint presentation

Hi - I have a simple 12 slide presentation which we are using at an event. We want to 'spruce' it up a bit and make it look a bit more slick but lack the PPT expertise ourselves... Could you provide a quote for how much you think this would cost and how much?

It is a fairly simple deck primarily made up of text and tables. We were hoping to have visual representation of some of the points. For example we talk about the need to "look ahead" which could be represented by a radar maybe.

Please get in touch :)

thanks,
Mark
