hey guys, I've mostly done residential work but today I was approached by a property manager about cleaning the sidewalks at a strip mall. They are unhappy with the company they have been using and even told me what they are paying. It's just shy of 15,000 sq foot of sidewalks 2 maybe 3 times a year. They are paying $900 and want me to bid it. My question, is .06/sq foot the right price.
