Most construction staffing agencies typically charge 40% to 70% above the worker's hourly wage. Virginia electricians earned a median of $30.24 an hour in May 2025, according to the Bureau of Labor Statistics, so that markup puts the bill rate at about $42 to $51 an hour per worker. On a 5-person crew working full time, the markup alone adds about $10,500 to $18,300 a month.
