Charisma,
This brings to mind another possibility. One could simply place the
objects on a scanner table and scan them, depending on how large they
are relative to the precision of the scanner and the importance of
the depth dimension. For transparent objects, one could use the light
source intended for transparencies.
Really, you haven't given us enough information to advise you on the
best solution. SEM would be fantastically expensive, but the
services are available commercially, and still expensive. There are
certainly photo attachments to microscopes, but they too are
expensive -- not something one would invest in for limited use, but
it might be possible to rent a set up. NIkon has made them for years.
You have an interesting name. How did it come to you? You must have
been a charismatic baby! Or were your parents members of the
charismatic movement in a Christian church?

Charisma,
My first question just has to be "what should the subject
magnification to the negative
(or digital file) be?" What DOF is required?
Then, one should (preferably) know the required magnification
to final print. One would then be able to provide some more
meaningful advice.
Three dimensional subjects might be better served using scanning
light photomacroscopy.
Or... perhaps, low magnification with greater DOF than film/direct
digital... one could employ
Scanning Electron Microscopy (B/W film, or digital) resulting in
less expense than $$ investment
in new hardware.... along with the time consuming learning curve
for a one-off job.

flexibility to be used on regular-sized objects. I am researching
Digital SLR cameras and various macro lens systems, but am really
unsure what it all means. I would love it if some actual
photographers who were used to working with macro photography
could recommend some systems? Also, we are not expert
photographers, so one with some automatic functionality would be
extremely helpful. Please respond to me directly, if possible.
Thanks in advance!

Your request for info brings up a few questions:
Seagoon: Any cases of frozen feet?
Eccles: You didn't order any cases of frozen feet!
