One thing that newbies tend to completely overlook is the business side of being a professional carpet cleaner. You are first and foremost a business person and that alone requires a wide range of skills and knowledge, so if you haven't been in business before I would suggest you spend a lot of time looking at the business aspects. You should have a well enough worked out financial plan that shows you to the nearest penny how much both your fixed and variable expenses are and have thought about all of the overheads and expenses your business will incur, regardless of whether you are busy or not. And most importantly of all you should know where your breakeven point is and what sales per week you need to achieve that, which in it's own right shows you the sales, advertising and marketing input you will need to make from day one in order to stay afloat. It is highly unlikely that you will go from zero to breakeven point any time soon, so you need to have a contingency fund sufficient to support your business until it can stand financially on its own, underestimate any of the above and you'll be on a hiding to nothing.
I wish you luck.
