What is the purpose of your website?
What do you want your website to accomplish?
Before you build your website, you need to decide what the purpose of your website is going to be? Is it going to be to sell products via the internet, or just to act as an on-line catalogue? Is it for your customers to book appointments with you, or for you to showcase your work? Or are you simply aiming to get an on-line presence and introduce your company to new customers? Do you want to help people to learn more about your company, or are you just looking to provide testimonials and directions to your office?
Once you know what you want your website to do, it will be easier to for your website designer to design it to fulfil those functions.
