I recommend you try to send this text message, I believe it supports quite a bit more customizing. (May be wrong)
Otherwise, you might want to try using a HUDMessage (Take a look at my easyinfo plugin, second page, unapproved) I believe EKS made a plugin to give you the coordinates of a HUD message.
