Luc Latulippe is a very popular illustrator-- who seems to have no qualms about making cold calls. He claims that 99% of illustrators are sending out postcards to get new work, and he uses cold-calling as a way to stand out. Luc even shares his script in this post. (Thanks to Tim Read of 5 Fingers Creative for sharing this link.)
Could this unusual no-fear attitude towards cold calls account for Luc's success?
If you want to learn how to do this yourself, watch for the Marketing Lab Workshop at the next Creative Freelancer Conference, August 26-28, 2009.

I know there are lots of designers coming to the Creative Freelancer Conference. But I'm guessing there are also some non-designers in the group, perhaps even some who (gasp!) don't own a copy of InDesign or Quark.
