It's been a long time since I encountered this problem, so my data may
be out of date. But in the past, there used to be companies listed in
the small ads (called "business card" ads) in the back of major
computer magazines like PC Magazine that did this sort of thing. They
charged about $500 some years back.
I also had a friend who solved this problem very creatively. He knew
neighbors who had teenage kids. He asked the kids who was the best
hacker they knew. He got in touch with the kid, and for the cost of a
video game (~$50), the kid came up with the password in no time! Some
may frown on this, but I found it very creative and the cause was
legit. Maybe it even showed the kid, if he had larcenious intentions
for his skills, that he could make money legitimately.
