Most private investigators charge an hourly rate for services such as surveillance or investigating a cheating spouse.  These rates are often negotiable, so be sure to agree on a price before hiring the PI to do the work.  Private Eyes usually charge a flat fee for services such as: a background check, missing person locate, court document retrieval, or processing serving.
