Add a job to the Draft job board to get your posting in front of a great audience of writers and editors.
It's $5 to post your position for 30 days. All I ask is that if you find someone from this job board (on the honor system), I'll send you a notification to pay $15. In other words:
$5 to post your position for 30 days. $15 only after you find someone for the position.
You're guaranteed to save most of your money unless you find a great candidate.
