as the saying goes, if you build it, they will come, or in the case of FF14, if you dont build it, the players will get together and build it themselves.
enter http://www.ffxivpro.com/. it's a player-generated searchable site, broken down by server, that effectively serves as a database of goods and services being offered or asked for. you link it to your official player profile and and can list goods you sell or are seeking, and for what prices, as well as search other goods, players, and services on your server. it even has messaging support that you can link into an e-mail, so people can more easily notify you if they cant find you in game.
the more people that use it, the stronger it gets, and the stronger it gets, the easier it is to find what you need. in this, the infancy of an economy, its a rather invaluable tool. so check it out, and if you like what you see, spread the word.
