That's the trade channel for WTB/WTS requests 😉 My advice, as a primarily eco person, is don't set up any structures yet. First get yourself the level 21 Freetrader class skill Economic Specialist so you can see the auction houses in all regions and study the Buy Orders. These are listings people are wanting someone to deliver to them. This will help you understand the market demand for different items. See you can find listings for those items you can deliver at a profit to begin with until you know what items are in demand. From there you can start to plan for your production lines. Don't forgot you can also switch nations on any time on the live servers, so you can also use the 10 production slots on those nations. Also study where the high infrastructure and low tax is. For Roberts, Bluefields, Puerto Cabezas, Belize and Bridgetown have basically no tax and maximum infrastructure for all nations.
