Website pricing

[mjrbaseball]

Hello.

I have been designing websites as a hobby for many years now, but never professionally. However, I have been paid for design work of single-frame ads (slides and hard-copy).

Now, someone I know is opening a new restaurant, and wants me to design his website. I'm ready to jump at the chance, but I don't know how what the going rate for something like this is. I don't want to sell myself short, but I don't want to ask for too much that he will change his mind and go elsewhere.

Can someone give me some guidelines?

Thank you.
