Well, Im not sure what level of website you need, but I've built websites that are modern, responsive, have chat, contact forms, and even some basic ecommerce functionality with checkout and credit card payments for under a couple thousand. It all depends on the tools you use, the complexity you need, and how greedy the company is that you are asking to build it for you. BTW I agree that there are some websites that are over $30k...but honestly....if you are a business doing less than say 5 - 10M a year, you shouldn't be worried about spending that much unless you are some AirBNB, or Uber type of ecommerce business.
Lets setup a call and I am confident I can save you hundreds if not thousands of dollars on a website. I have plenty of examples I can share as well.
