Simple Powerpoint Makeover

I'm looking for someone who can do a quick workaround on a 16 page powerpoint presentation.

We've been given a pitch by a friendly rival firm and we want to rebrand it as our own.

Basically it needs the slide background altering to add the client's branding/logo - all supplied, some dodgy clipart needs removing and some of the slides could do with a little bit of a tidy.

Adding of branding means including a branded footer and logo to the slides, which means some of the images may need shifting around.

Design experience would be beneficial as a few colours and fonts will also need changing.

Please bid for the full job, and how long you expect it to take.

Thanks
John
