This is what you should do, advertise your business within your apartment, you already have a ready market, just make them aware that you are willing to provide services. Once you get the demand, go out and hire temporary workers, the market is flooded right now with cheap labor so you shouldnt have a problem. If you need workers on the same day due to high demand, go to Home Depot, you will find ready labor. Get the job done, then go out and buy your own supplies, this way you will be able to charge more coz no professional company uses the clients supplies. Then create a charging schedule, you can charge a flat rate for a small one bedroom but you have to adjust charges for bigger messier houses, also itemize and charge extra for the extra stuff like doing laundry, dishes etc. Once you get all the residents at your apartment, advertise in the penny saver or paper and get more clients, dont be afraid of large volumes, there is cheap labor available and you can pay them per hour. Have a standard rule that the cleaning is done within an hour or two to avoid shirking from the employees. Lastly register your company and pay taxes coz uncle Sam does not play, you may also want to make sure your employees are eligible to work coz cousin Barry is not playing either! Good luck.
