How much do you charge for a website?

I'm interested in doing some web development for businesses who are willing to hire me to make one for them, but I wouldn't know whats a reasonable amount to charge. What's a ballpark number you charge a client for a website? I know it might depend but any numbers would help.

Charge as much as you can get away with -- and make sure you bill by the hour and start with a reasonable statement of work.

Any time estimate you give you should probably at least double -- freelancers typically get themselves into trouble by quoting either too low an hourly rate, too low of a flat fee, a too low time estimate for completion, or the customer keeps constantly changing what they want...
