Hello Erkka,
first of all congratulations for what you have accomplished.
When I found your blog, I felt good, because reading your article "Life in the finnish woods", I found myself in the words you wrote. I feel depressed too, I also dream, like you, to live in a house in the woods in Finland, away from the country where I live (Italy), I also want to return to a simpler life, in the wildness. I also, unfortunately, at the moment have no money even if I have a job (which I hate) that could let me set aside some money. Many people think that what I want to do is unrealistic, but your blog shows the opposite.
If you do not mind I would like to ask you some "technical" questions. For example, I was wondering how you made the connections for electric current? Do you have solar panels?
Do you know any Finnish website to find land for sale?
Thank you in advance for your answer and good luck for all
Luigi
