"she found that there are writers on eLance who charge $10 for an entire blog post and $20 for a press release."
If you are selling something on a small scale (such as what your wife is doing) it's a wrong assumption to think that everyone knows the going rate for something in the marketplace. People overpay for products and services all the time because of convenience, FUD, or simply not knowing what a typical price in the marketplace is. Sometimes of course they also infer quality into pricing thinking that it is either inferior or that there must be some catch to low pricing as well. While at a certain point (large numbers) you can get hurt, at a smaller level it is not as much of an issue.
"based on the value they would generate for her consulting clients"
Agree. That is the key in many cases to the question of "what to charge" for something (once again it definitely depends on the scale of what you are doing obviously).
