From past experiences, i would not hire anyone until you absolutely need them. why?
1) How much business do you currently have? do you have enough hours to keep an employee happy with their paycheck.
2) A business just starting off needs a good reputation and happy clients to recommend your company to their family & friends. In the beginning, clean the houses, get to know the clients & you will find you get more recommendations than a employee will ever get you. You (the owner) will try 10x harder to keep a client happy than an employee ever will.
3) After paying employee wages, employment taxes & workers comp, how much is actually left for you?
My suggestions: Get out there, get clients and learn. Cleaning houses isn't hard and you will learn from your mistakes on the way.
