Need some help for ad pricing

You guys are the pros at clicks, links and so on. Figure you could give me a pricing model for our site. It's a social site, currently using Adwords and have bought a few spots on other sites. See how those go.
Want to add to this, do not know what the term is, but have other sites sign up with us and we run ads on their sites. Thinking about the 40 to 60 cents per click through. ~1.00 for each signup.
Got the code done so it's basically ready to go.
Too low? Too high?
Thanks

If you're getting a boat load of traffic than price your ads around 20% - 25% cheaper than your competitors so you can attract more advertisers.

I would start my ads at like $0.25 per click and then increase or decrease depending on how many advertisers start joining.

Thanks for the reply Razzy. But I want to buy space on other sites. Have all the ppv on my sites I can handle right now. Need to drive more traffic to increase the views.
