A neighbor showed me a set of nested classifiers for soil science ... cute, expensive and small production.  One might find prospector's classifyer's ... for small scale production ... several cooking tools can do nearly as well to sift soil or drain noodles, but still on a small scale.  the variouys size plastic wash tubs are great for mixing and moving soil around.
Having a classifyer constructed on a sturdy frame with stainless steel hardware cloth seems functional if something else doesn't present itself.
Am not presently in LOS, but I have a Thai wheel barrow ... square box/bed, 2-wheeler, hinged box/bed for dumping ... and a compost pile to sift for the garden.  For sifter I have a metal bread rack (from a bakery) that fits over the box and a plastic nursery flat with c.7mm square holes ... placing the compost into the nursery flat and giggling it about the bread rack does the job ... and having the prduct conveniently in the little dumping wheelbarrow is very convenient.
