I have my own cleaning business and I have no clue what to charge.. I've read everything from .15 to .25... I have a great friend who owns a construction business who said she would sub me out to clean and asked me what I would charge... HELP? We have a job to clean a 5000 sq ft basement coming up and I'm not sure what to charge. I live in the DC area and work all around marlyand, virginia, and DC.
