We do not charge for conducting an investigation. We will ask for travel
reimbursement, which can include gas, airline tickets, phone and tolls.
We generally travel by car whenever possible to keep the costs to a
minimum. Due to the reality that there are always those who can not
financially reimburse this amount, the fee will vary on case by case
basis.

Um… what?  Surely this is for a private "investigation" not appearing on the show, and travel to cases appearing on the show is paid for from the show's budget.  Right?  I can't imagine a home owner being asked to bankroll a television production.  Someone claiming to be Zaffis left a comment but it doesn't touch on this.  Does anyone know more about this?
