Moreover, it's important to designate someone who will be in charge of overseeing the whole process and making sure everything gets done. It's also cost effective- you don't need to pay for all the supplies, saving you money in the long run. Secondly, make sure the company can provide reliable services that meet your needs and expectations. First off, it's essential to find a cleaning company that is reliable and trustworthy. Every employee should have a designated desk space where all important items are stored away neatly - this will significantly reduce dusting time! Moreover, try adding wall storage units for additional storage needs such as books or files. On average, though, you can expect to pay anywhere between $30 - $90 per hour for quality service.
