Squeaky, you are going to get better information from an industry forum but I will tell you this. You are looking at the money from a layperson's point of view. If I employed you and sent you out at $12 per hour I would have to bill the customer $45 per hour to make a few pennies myself. Direct and indirect costs for the job, tax matching, operational expense, downtime (you are paid for the time you travel betwen jobs, right), company profit margins.. these have to be added to your base salary. Marketing, selling, administration, analyzation.. these things all cost money and make up your expenses as a business owner. I then have to add what I want to make on top of all that. You may think you understand what it costs to just "clean" but you do not. That is not an indictment but I do hope it makes you think.
Before you do anything else, go out and buy a book called E-myth. It will help you understand the difference between owning a business and owning a job which one may THINK is a business. Once you understand your operating costs, you can utilize the knowlege you have about your efficiency rate and bill accordingly. As a one person show always bill more than a company that has more employees does. You may think you have less expenses than a large company but their efficiency is so much greater they will put you out of business if you try to beat them on price.
