How about this:
Everyday they're three different guild point items you can choose to turn in. Tier one, worth little but easy to get. Tier two, decent amount of points, not easy, but not difficult to get. Tier three, worth a lot but very difficult to get (perhaps making it an item that you can't buy).
I find it annoying that there are many days where you can only get 1k guild points. Considering how much certain (key) items cost and the day and age this game is in I think some change is necessary. If someone just begins this game and decides to level a craft, it is very likely that he will never be able to achieve certain items. It just takes too much time.
I think having something like the above where you have a choice to use your time to get a difficult item that rewards 3-5k guild points a day would help.
