Temp firms generally charge a fixed percentage greater than the hourly cost of a worker. For basic jobs, this can translate to total charges of $9 to $18 per hour. Skilled temps tend to be much more expensive. Technical or professional temps may cost up to $30 per hour.

Most firms offer discounts off their published rates. Even if you plan to use temporary services infrequently, it is usually worth negotiating rates upfront to reduce the overall cost.
