I know this question is hard to answer there are a lot of variables.  But anyone with any experience here could help me.  Say I had 5000 unique visitors a day to my .nz website, how much could I expect to charge for an advertising space (like a banner or such) that has to do with the websites topic etc?  How much for google adsense?

Any ideas at all will help, it's a very vague question I know conversion rates and so on, I just want some idea then hopefully I can track down whether my idea is viable.

I've come up with a website idea, there's a rough website that does something similar that's getting about 5000 unique views daily.  But the website itself is pretty cumbersome and hasn't fully captured it's market.  I have a new way to expand the idea.  It's a very simple website still, just the way to display the information will be my competitive edge.  As I said just trying to get an idea on potential future revenue to see whether it's worth pursuing.

Thanks
