restoring audio from microcassette ...

hi, I have a friend who sent me this note & I told
him that I would send it to this list to get a
professional opinion on it. Now, I don't know the
state of his tape and whether or not its very fragile,
as he doesn't specify how old the tape is, but I think
the tape won't be more than 10 years old. I also
have a copy of adobe audition that has some denoising
and dehiss filters. I could just as quickly see that he's
got a copy of this, get him to output the signal from
a microcassette player and work with him on
it, or, say, turn the thing over to someone to do,
but I fear that this will be prohibitively expensive,
as in not sure his few hundred dollars budget will
do. Does anyone here have any suggestions or know of
any group dealing with things like this:

Hi Phil,

I have a microcassette
recording of an ordinary half-hour conversation that I would like to play
back and transcribe. This recording took place many years ago in an
office (not a recording studio); there is a lot of hiss in the recording,
and in general, the voices of some of the participants are quiet and
indistinct in places. What is the best way to enhance the recording so
that all of the voices are as audible as possible? (I believe this process
is called "audio restoration") Should I somehow get it into a computer
and then apply a filter to remove the high-frequency components? Should I
give it to a studio? This is a very special recording, and I would like to
get as clear a version of it as I can, and I am willing to pay for it
within reason (say, as much as a few hundred dollars if need be). All
suggestions would be welcome.
