I think there's great profit in doing farmville, planting enigma seeds, getting golden lotus (usually get 5-8 every 24 hours+other herbs) and selling flasks from golden lotus, as well as potions from the remaining herbs.
Otherwise, I think it's best to sell during raid nights, but that might depend on your server. If you're on a small server, you might not make as much on raid nights as you would on a large server.
Obviously, make belt buckles each day from living steel transmutes (but be careful of trillium prices - especially now that people need it for their legendary quest).
