It really depends on what sort of website you need. If you need a simple informational website for a small business, you'll probably find that it doesn't cost too much. However, if you need a really stylish website with a lot of features then it could cost you a lot more.
It also depends on what company you work with. My advice would be to shop around a little and get some different quotes. When I was looking for a professional website designer, I search for website designer Kent on google. I found a few companies, and some were quoting way too much for what I wanted. Then I found this company, https://www.mediainabox.co.uk/, and their rates were really reasonable. It would be hard to say exactly how much you should expect to pay because I don't know where you live, or what type of site you're looking for, but I can say that what I paid for my site was very reasonable, and certainly didn't break the bank.
