If a hobbiest figure what your time is worth. A local shop will charge
like $60.00 and hour + tool wear. This type of wood will wear out
knives and tools, figure that in also and the time to replace the
blades, ship them, drive them.

It would cost the owner a few hundred to buy a decent lunchbox planer,
then they need dust disposal as Cocobola is a cargingen and having that
dust/chips could cause you trouble without good chip collection.

Jointing is about $0.50 to $1.00 a bf at the local yard, so I think you
are low.
