I think price also depends quite a bit on what you want.
Is it just 4 or 5 pages? or more complex? Does he want an online shop? That would be more.
My last website I needed, including online shop and online payments etc., I got a student webdesigner, it was his first ever commercial website he had done so he only charged £500, but got a website for his portfolio out of it, so worked well for both of us.
Downside was he didn't always know how to do what I wanted and the whole process took a little longer as he was learning on the job.
