My own experience is that it all depends on the skills of the salesman.
Really!
I have seen a guy sell ads on a site that wasn't even live yet, at exorbitant prices, because he was a brilliant salesman and he personalized the sale really well.
It seems to me that if the vertical market in questions is full of "internet naive" potential advertisers, you can do really well. Conversely, the more internet savvy are your potential advertisers, the less you are likely to get out of them (since they know what the "going price" should roughly be).
The other sales skill I've seen is to turn a boring ad sale into a "partnership" or a "joint venture"... meaning that a good salesman can drill deeper into the opportunity and create something of much greater value for both parties than a mere ad sale.
None of this works at the scale of an "Adwords" operation, of course, where everything is streamlined and impersonal, but if you're selling advertising to a very specific market of potential advertisers, and you can prove your "stranglehold" of their target audience, and you have the control to tailor specific and different deals for different advertisers, then you can do a lot of good stuff.
Unfortunately it's really really hard to give out specific numbers, because invariably they don't apply, or may be disproven in your specific case.
