As we are originally a local Thai based agency all our work is guarenteed and authenticated, we carry liability insurance and are licensed investigators in Thailand
This enables us if needed to present our evidence in a court of law I can guarantee you that other investigators you are thinking of hiring are un-licensed and actually working illegally in Thailand leaving you exposed when the service you pay for is not performed or legal problems arise through illegal activities performed by these people as they have no license to practice.
In the real world that we live and where your investigation will probably be conducted (Thailand) we put all our resources into every job which means we use the correct number of staff, the right staff depending on the circumstances of the job and enough vehicles to cover every possibility this is why we have teams and not individuals perfoming surveillance and undercover work or you may find yourself paying a company that will lose the subject within the first 30 minutes and then possible just tell you lies to cover mistakes they made.
All our detectives are trained at our detective training academy where they also go out in the field on real operations with experienced agents to gain essential skills no class room can ever teach. All our agents carry photographic and/or video equipment and always produce evidence that they were where they said doing what they are paid to do, even if its just watching a building for hours waiting for the subject, not exciting i know but proof for you the customer
