Wanted: succulent plant cuttings

Has anyone any outdoor succulent plants (house leek/stonecrop etc) that I could take some cuttings from? I'm struggling to source some for a gardening project. I can swap you for some jolly nice Heucheras (dark red and a light coppery colour).

This is what I'm trying to do: http://news.ucsc.edu/2011/11/images/succulent-frame-325.jpg
