Try Edmund Scientific #52467.   They are surplus gearmotors, and
they supply 90 RPM @ 12 volts.  I don't know how much torque they
supply, or how much current they draw ( I haven't hooked them up
to my test rig yet ).  They were the closest I could find when I was
scouring sources with needs similar to yours.  They seem to be
pretty torquey for their size.

Hope it helps...
