Ask HN: How do you generate leads as a new software consultant?

Hey HN! A few days ago I decided to finally register a business with my current home, the nation of Finland. I'm going to be here for a while so I figured there's no time like the present.

I have no sales background whatsoever, though, and I don't even know what I don't know yet. Do any of you have tips on how to land that very first customer, and then hopefully the second one after that too?
