I have also done some bespoke writing for corporate clients of various sizes and backgrounds. As part of my work for Burson-Marsteller, I write a weekly internet newsletter called dotCOMagain. The idea is to explain things that concern geeks to an audience of non-geeks, in a way that will hopefully appeal to everyone. Sometimes, it's also quite funny. Please feel free to subscribe , or email me if you would like me to do it for you.
Feedback is good.
