Job requires computer graphics skills including Photoshop,
Illustrator, Quark, etc. as well as use of traditional art media,
audio-visual design, photography, communication with public, and many
other responsibilities.  I imagine Mr. McCall can forward the e-mail I
saw (2 pages of "primary skills" required) to interested people.

Good luck!

At least cost of living should be low in Nashville, no?
