Since bounty hunters are paid on commission it would be tought to determine their pay. There are a lot of factors: Their experience and success rate, how many bails companies they do work for and how hard they work. This is a job that require a lot of discipline and a lot of motivation.
I am a bounty hunter that works for a large bail company in California. I know what I make but it would be difficult to guess the pay of a contractor. The good ones can make 200k a year. New guys are going to be lucky to make 30k a year. I hope this helps
