MapleStory Chaos: Profession Recipe Guide

Just a quick question: How many mules do I need to create everysingle plate? I mean, my main character will be focusing on crafting rings while my mule creates the plates. You think I might need 2 miner jobs? This is for getting lvl 10 jeweler in 15 days.

Thanks in advance.

Edit: I have another question. =O I saw on Spadow's blog that there was also an Event involving the mining profession. It said that when you reach lvl 7 mining, they will give you a Gold Pickaxe and Bag with more slots.
Now, my question is: How many days do we have for this event?

Because if it's the same as the Dark Angelic Ring, then I don't think I can complete both of them in 15 days. x_x
