What is the normal rate for proof-reading?

I've been offered a one-off proof-reading job by some programming company and they have asked me how much I would like to be paid. Having never done this work before, I'm wondering what is a normal rate in Finland? I would need to proof-read about 100 pages of text.

not sure if this is high or low or how different from IT industry, but FYI Tampere University pays around 10 to 15 e/page for proofing and editing an academic article.
