Looking for help with PowerPoint or Keynote presentation

I'm preparing a presentation using either PowerPoint or Keynote (I'm both PC and Mac) for use in a workshop. I am writing all the text but need help with formatting, adding graphics and pictures, etc. A lot of the work can be done remotely but we will need to get together initially and periodically to review the work. I am in West Marin (Lagunitas).

Please reply privately with your experience, rates and examples of your work. I am looking for someone who is very skilled. If you're still learning or haven't used the software in awhile, please don't respond.

Thanks
Linda
