Maybe instead use FFXIV Party Making system.
It's basically a list of groups (that made themselves visible on that list), with what they want to do (instance, PvP, etc), and classes of party members, and empty spots that can be configured to search for role (for example, only healers will be able to enter on slot 4). It can be clicked to view more info, a description written by party leader, and party leader's name, and quick "message leader" button. It even has an option to choose languages accepted.
