Free standing foils (polycrystalline) are routine in the nuclear and
high energy atomic collision physics community -- you buy films deposited
on glass slides, float them off onto the surface of water, and then pick them
up (VERY carefully, especially if only 200 A) onto a holder.  Talk to 
your nearest accelerator jockeys for the latest info about sources.

As far as single crystal films, they do exist -- I have been on experiments
using them (years ago), but I have no idea where the best sources are.
I would expect if you found out typical sources of the polycrystalline films
the suppliers would know who does the single crystal foils.
