I love HN for its great community. Therefore I want to ask about your experiences how to start a online marketplace. The development is done, so we want to start with the marketing channel. We like to pitch craftsmen in one single city. How would you do this? What channel would you use? In my opinion it is difficult to use adwords or fb because the owner of those small business don't use it. So we are still thinking about which primary channel we shall use. In my opinion direct mailing via postal service is the only way. What do you think? Thank you.
