I have often helped the public with searching if I have the extra time.  I also do it as a courtesy and not for profit.  The general public does not understand as an example "no record" or why their deed they thought was filed isn't there and then a charge to boot!  Usually, they have no comprehension of records and law so its best not to charge them anything.  Its a slipperly slope.  We are not attorneys who have the right to charge for our advice.  JL
