Fix templates in Microsoft Word and Powerpoint

My company has some templates for letterhead and presentations that we want edited. For example we want the body text font changed. We want someone with specific experience working on Microsoft Office templates. If you do not have examples of this experience please do not apply. We don't believe this work will require more than 2 to 3 hours work as the templates already exist and we're looking at less than 10 changes to the existing templates. Thanks.
