cms for speaker

I need a very simple content management system for a potential client who is a public speaker. I have not won job yet. I need to present an estimate. I would design site in html. You would create a cms for the site. Client would login and be able to edit copy, add pdf files, add links, add photos. I would like the font to be locked so client cannot modify that portion. Site will be super simple with 3-4 pages. Nothing fancy. They just want a web presence.
