Worth raising Blacksmithing/Tailoring for a newbie?

[Flash]

I'm out farming pelts and silk in EC at the moment, and have been sharpening rusty weapons to get my blacksmith up (at 16) now. I plan on getting my smith/tailoring as high as I can without making an investment (I.E farming the mats myself).

How long would it take me, unfunded, to get into the 100s from scratch, and is it worth my time to be doing this right now? I really wanna be high enough to make a full suit of Wu's Fighting Armor before WC, as I'll need the upgrade by then.
