Totally depends on the website requirements. Do you want it to be selfhosted or can it be a wordpress site? Is it just a billboard with some text on it? Does it need client side logic? Do you need server side support for authentication/tracking history/ect? Does it need to be purely functional, aesthetical, or both? Give us some more details for a better estimate.
Usually a full web stack developer's price is $15-30 / hr. You can maybe cheaper if you hire just a graphic designer or just a back end developer.
