There are some dozen faces designed by Jos Buivenga available for free download from Ex Ljbris Font Foundry. Fontin Sans is a complete family and completely free for both personal and commercial use. I would have direct downloads available but Jos has requested that you stop by yourself and take a gander at all the licensing stuff. Have at it!
