Services are regularly charged at an hourly rate plus expenses. The importance of not only conducting an effective, but also an efficient investigation has become a paramount for many law firms, individual and business that often work with a predetermined budget. Our Agency is very aware of the budget restrains often placed on our clients and have implemented aggressive cost control measures to ensure that our clients receive the most effective, reliable investigations within the budget parameters. These measures include supervisory review of assignments allowing us to schedule tasks in conjunction with others thus minimizing travel and field time as well as expenses.
HOURLY RATE: Although our services are charged at an hourly rate, we have developed various ALL-INCLUSIVE hourly rates or DAILY FLAT-RATE pricing plans and services that can be tailored to the specific needs of the client. This is one more method of aggressively controlling costs.
