Trying to make the world a better place and helping people out well and good, but starting a business is all about that cash money. You would be hard pressed justifying the amount of time you are spending on any business that you have chosen to start if it has not begun generating a decent enough cash flow once all has been said and is now out of the way, so you might want to start thinking about how you can charge your customers after you have provided their requested services and your rate for said services is perhaps the first thing that you should get squared away.
The reason behind this is that once you have figured out an ideal rate for Pearland power washing, suffice it to say that everything else will start to fall into place a lot more easily than might have been the case otherwise. The best way to charge for the services that you are marketing and trying to show to a lot of different people is to break the charges down on a per square foot basis.
Charging ten cents per square foot is a pretty solid place for you to start because of the fact that it allows you to undercut your competition and price them out of the market that you are trying to enter and potentially eventually dominate. Ten cents per square foot will ensure that you are able to earn a reasonable amount of profit from your pursuits, but it would not be so high that your customers would want to avoid hiring you because they might see no point in avoiding some of your competitor brands.
