EcoEnchants integrates with Essentials or CMI so you can just use /enchant to apply the enchantments. It also works with kits, /give, and any other feature that interacts with enchantments. All the enchantments can be obtained through Enchanting Tables, Villagers, and even chests in Strongholds, End Cities, Pyramids, etc.
