The Wisconsin Private
Investigator Directory
Using a Local Private Investigator is usually the best
way to have an investigation conducted. While national
firms offer convenience and are usually able to conduct
information searches well, they will not usually be able
to provide you with a quality investigation that requires
surveillance. National firms contract to smaller
independent investigators and simply charge higher
rates. In many cases if there is a payment dispute you
will find yourself unable to easily get support from the
actual surveillance investigator.
