Just to add my 2 cents, Amy.
A copy writer or a marketing agency etc. can help make everything more slick and better looking.Work better emotionally, aesthetically etc.
However, the core of the message has to come from you and not anybody else. It has to reflect who you are and your personality. And its reflection in your business has to come through. Which means that you have to sit down and think through it.
Otherwise it will not reflect who you are and it will not be any different than other web sites that they've already done before.
So............... get thinking.
And it does not have to be "very" unique. How many unique sites do you really know in each given industry. It has to reflect your passion and professionalism and demonstrate with text and graphics, the message you want your potential clients to receive. And as a result make them want to call or book a cleaning. In other words- want to do business with you.
