>>If your needs are not unusual, first look around for templates that are already available ( assuming you don't just want to hire a web designer ) If you're doing ASP .net apps Expression Web templates is a good place to start. Just google that and you'll get the idea.

You should definitely take a look at Balsamiq, then, which I mentioned before. One thing I like about it is that the output actually does look like pencil and paper. The MSDN review mentions that more polished prototypes can delude users into thinking it is further along than it is. Have definitely seen that myself.
