You pay according to what you want of your website. The more requirements come with the higher prices. I am about to change my website, the budget is also one of my concern. I want my website professionally and beautifully made, but also with a reasonable price, thus I am looking for the best cost performance for my website.
There is no price to high, just clients that don't want to pay it. Honestly just look around, if you contacted 20 designers with the same specifications, you would get 20 different quotes. And I'm pretty sure the ranges would be all over the place.
