Well... one possible (temporary) solution to this particular dilemma comes
from the world of machineing (metal cutting, etc) where small
shops/hobbiests frequently obtain equipment (mills, lathes, etc.) that is
designed for three phase power.

Rather than replace the motors (an aggrivating and expensive proposition),
there are a number of sources for three phase 'converters' which take
single phase power (or perhaps two phase for really heavy load situations)
and through (most often) a motor/generator combination output real (or
close enough) three phase power for the application.

I would not be surprised of some of the larger equipment rental places had
such critters available for rental (or sale for the long term applications).

Just my two cents worth...
