Okay, just to help end this quickly and quietly:

There is a month left. If you were to get them all their seals it is still improbable that you will complete all the other legs of the quest done. I'm not saying it isn't possible - there are groups that do this enough and with superb efficiency. But if these players waited until now to get to the hamlet point then I doubt they have the experience and cohesion to complete the ores, salts, extreme, and everything else in ~30 days. This is factoring in the fact that you stated multiple people.

In short, while it is possible that you could finish this before the month is up it is highly improbable. Therefore, such a request ought to be left alone.
