maybe you should not spend 300k on gear and find yourself a friendly crafter instead.
I did something fairly easy: a friend of mine levels up miner, weaver, leatherworker. I level up botanist, alchemist, culinarian.
we send each other what we need, farm enemies together to get drops, and the likes. my brd and my whm have been running around in HQ gear pretty much the entire time - my friend in turn keeps getting HQ pots and food from me. we're not paying anything (and still making a profit by selling 'left-overs')
granted I guess you mean lvl 50 stuff with your 300k gear (or at least I HOPE that's what you mean), but my friend and I are fine in that regard, too. I can get the mats, after all, and if all else fails there's still the 'dungeon farmers' in our FC - whom we also provide with free mats/gear/pots/food.
