That's an incredibly low CPM, especially since your visitors will almost solely be from Finland, right? It's not uncommon to earn ~$1k/month purely from ads on blogs with ~100k unique visitors/month. So your CPM seems >20 times less than that.

Do the better paying ad networks all reject you solely because of the language?

I don't know why I get rejected. I don't even get replies to my requests. But I am guessing the language is important part of it.
