Hi
I'm an Adelaide person too.
I run a solo graphic design service ( Red Ripple Design) based in the Adelaide Hills but servicing anywhere/everywhere. Business has been growing steadily and I now regularly sub-contract staff to do various parts of projects with me.
Check out my Flying Solo profile. Also, I started the Graphic Designer's Group on here.
My website is

Cheers!
