Private investigators do a broad range of work, an example is general surveillance. With general surveillance their typical hourly rate is between $100 to $300, depending on experience. They also do background checks, finding a missing person, tracking family members’ movements, and general investigation related to criminal cases, among others. 

Based on our research, the average cost of a 30-hour case is between SGD$2,000 to $4,000. Thus, if you happen to require a job that spans to more hours or days, expect to pay in lump sum ranging from SGD$1,000 to $6,000.
