I live in Macon, which has one of the lowest costs of living in the country. An entry-level drafter will make around $8-$9/hour, $16/hour is about the ceiling for a senior drafter. This is excluding any 3D work or specialized skills. Basic 2D drafting, redlines and such.

Of course, you go to Atlanta (about an hour away) and that entry-level number jumps to around $12-$13/hour and a senior can make up to $26/hour or so.
