If you want good money try doing a few runs of meatheads deli. It won't take long even at your level and you will make about 1000 gold each run. Also you have a chance (I think it's about 1 in 100) of getting a gem from the bosses which can sell for about 8000

Add my Mage to your friends list and if I see you online I'll do a few runs of meatheads deli with you
