Dorothy,    Maybe those ideas will help some, but I think a "real
motivation" for a company to decide to pay you is if you know
the bank, loan company for whom the searches were done, you
can contact them and let them know you were not paid for
your efforts.  Perhaps if they feel your client is stiffing the
people who do work for them, they may decide to find a
more honorable company to place their orders with.

Just a thought.   Send your creditor a copy of the letter you
plan to send to the bank, etc., and offer them a chance to
not have it sent by getting you paid within 48 hours, etc...
