Cheapest methods of polishing parquet flooring

I need about 30 sqm of Parkett flooring to be polished/cleaned- can anyone recommend someone who can do this, or perhaps where I can hire the equipment to be able to do it myself? I have been quoted so far about €600, but think I can get it for cheaper.

Thanks,
Kent.

We talked about something related a while back: Repairing and/or resurfacing a hardwood floor, Tips on fixing a parquet, suggested companies etc.

Thick, woolen socks + furniture polish & pretend you're a speed skater. Cheapest method I know.

A childhood visit to the hospital says that depends on the amount of splinters in the parquet.
