Is really ANY tradeskill an option? If yes and you want to make a GM without loosing too much money pick fletching, the discord arrow recipes can get you to 227 at very low cost and the shadow tipped acrylia arrow which has a triv 268 will bring you to GM. It uses arrowheads which can be smithed at 117 with components that are on sale in the bzaar quite inexpensive.
Check
EQTraders for more info.
Of course fletching is only advisable if at least one of your toons shoots lots of arrows (which means NOT ONLY to pull) because near to no one buys them in the bazaar ;-)
