To be honest James, if you love cleaning and love the night shift you should just work for someone else. Owning a cleaning business really has nothing to do with cleaning but has everything to do with owning and running a business. Even if you want to be 1 guy that works for him self you will still have to do the same things a business with employees do. You will need to market your business. You will need to give bids. You will need to follow up. You will need to order your supplies. You will need to do all the paper work. And I'm sure I'm forgetting a thing or 3. And then being a 1 guy cleaning service on top of all that you will need to also clean.
