PowerPoint to look good

I have an 18-page PowerPoint presentation that needs proper formatting to make it look good.

Also to introduce a suggestion of branding (I have a logo and "look" already per our website) and copyright info per page.

It doesn't want over designing. Just a simple and professional presentation of the content I have already.

I have a bitmap of the logo that might be useful, and a spotty background graphic.

The screen in the presentation room is small and high up, so text needs to be clear and large.

I reckon it should be no more than a two-hour job.

I need delivery on Tuesday 29 April for room set up on 30 April and the workshop on 1 May.

Thanks, Cally Robson
