Checked EULA

2.2 Real Money Trading, Farming and Power-Leveling. You may not sell, purchase or exchange for real-world money or value any ... in-game services, ...

So yes, it is against the ToS because its an in-game service they are providing (clearing the quest)

Except they're not trading the service for "real-world money or value," they're trading the service for in-game money, which is no different than someone paying you gil to power-level their character; it's the difference between paying gil for someone to do it and paying someone with real money outside the game to do it .

The whole part I highlighted because they go together; it's "real-world money or value" not "real-world money" or "value." This is to cover using money, gold, any sort of real-world goods, etc. being used as a trade for in-game services.
