I've heard of people using "monopods" for astronomy with binoculars.
There
may be something designed for binocular use available in telescope and
optics shops.

You could try the Argos catalogue. A tip I learned here a while ago is to
use an up-turned broom. Someone else suggested a thing for cleaning windows
as it's telescopic so can be set to the right hight for you. I found the
broom to work well but was too short.
