Buy a professional-grade and do it yourself. Lowes sells a $499 Simpson, "tri-plex" or something pump (servicable), and a Kohler engine. Mine has already paid for itself in one house and driveway wash.
We had Ed with Under Pressure Power Washing do our home last year. About to contact him about doing it again. He did an excellent job! (919) 369-6077
