Your first contact will always be with the principal operator who will discuss your problem and make recommendations for a specialist operator for your particular circumstances. The investigator will provide continual information and feedback to you during the job. Information is detailed and confidential. Whatever evidence you require, we will provide - documentation, tapes, a final report - they are part of the service. How Much Will It Cost You? The cost of an investigation varies on your exact requirements. Some assignments are priced on a set rate based on a set result that the customer is looking for - for example most missing persons investigations, or database research can be fixed once we have discussed your goals. Most investigations however are charged at an hourly rate because we don’t actually know how long the investigation may take - charging an hourly rate is the only fair way for both you and for us. General surveillance rates commence at $95 per hour all inclusive of GST, mileage, travel time, video, report and regular updates. The hourly rate can increase for other field based work depending on the specialty involved.
