If you have a business, a website can be your shop window to the world. When I worked in a shop back in the 1980s, the boss insisted that the doors were always open. The fewer barriers people have to your wares, the more likely they are to buy what you're offering.
What do you need from a website? Well, this site fulfils all my needs as a small business. People can find out what I do and get in touch with me. They can also find me on Facebook and LinkedIn.
Note that there's no blog or anything that I have to keep up-to-date on here either. I've kept it as low-maintenance as possible; time is money, and I'm not sure how much value there would be in spending hours every day updating things.
What most businesses don't need is something massively complex – very few of us are Amazon. Keep it short and simple to keep your costs down.
If you'd like to see what I can do for you, contact me and let's talk.
