I hate to discourage anyone interested in composting, but efficient
composting requires a large enough mass to build up internal heat.
Half a cubic yard or so is a minimum. You probably don't have enough
space for that, and you certainly don't have enough raw material.

Your best bet is to buy a the vinyl composting bin of the type sold at
many garden centers and home improvement stores. It will contain the
materials, which is both a sanitary and aesthetic advantage when space
is limited, and it might accelerate decomposition a little by
providing thermal insulation. But be prepared for a composting process
that takes six to twelve months.
