Just do what I did... find an FC member capable of HQing the Lv63 set, since that is rather easy to get. Get the materials (6x Gyuki Leather, 6x Koppranickel Ingots, and... I think 2... of that thread you harvest from Ruby Sea?) and get the whole set made.

With HQs, you'll have ~670GP which is more than enough to activate Lv70 +Gather nodes (which ask for 610-640). I think there's one "crazy awesome" one that asks for 700... but meh. I can live without it.
