Palan and I have struggled with the same issues, but we solved it like this .... parked an alt in Rathe Mountains and get online at unusual times (like 8am Saturday morning). Drink coffee and hunt hill giants ... they drop about 42 plat a piece as well as weapons and gems.
The key? It's a brutal zone and leve 65 people KS green mobs all the time ... so only hunt there if there are 7 or less people in the zone. If there get to be too many people? We log and live to hunt another day.
This doesn't involve any bazaar time, as the cash is right on the mob. No waiting
Also, I've got my level 44 druid bound there and she gets great xp on the HGs.
Personally I can barely move in the bazaar, so I like solutions that don't require me setting up a vendor. Although, Palan has a better computer so he does have a vendor we try to use to sell our stuff.
