There are relatively few avenues for selling your profession's wares. The first, and probably the most universal, is to create your trade goods and then list them on the auction house. This is a pretty common channel for selling trade goods. As such, there's more than a few techniques and arts to getting the most out of working the auction house. Check out Gold Capped, for example, to pick up a lot of great advice on how to work the AH.
The second way to sell your goods is via small-scale professions gathering. We talked a few weeks ago about how to get together a crafting bazaar. The advantage to a crafting bazaar is that you get a lot of exposure from a lot of people. If your event is fairly well attended, then you're going to get a lot of different customers cruising to buy crafting goods. It's especially advantageous to spend time working with a consumer in a bazaar environment, because you have face-to-face interaction during which you can try and upsell the client. You can check out all of their gear and enchants, and make recommendations for things they might want to purchase to improve their performance.
There's a middle ground between those two methods, however, and it combines a lot of the best traits of the crafting bazaar with the open, free market of the auction house. By advertising your profession on Trade, the official forums, and word of mouth, you can get in touch with prospective customers while still respecting and interacting with your server's overall economy. You get the chance to meet someone "face-to-face" (or, at least, whisper-to-whisper) and you get the same chance to review the gear that you would in the bazaar. However, you don't have to wait for a special location or particular time in order to meet those folks.
Considering how important word-of-mouth can be to growing a network of steady customers, we should take the time to review a few tips for advertising your profession.
