My easiest money maker is Mine Saronite, Prospect it, take the blues and transmure into epic uncut gems and then sell. The mining step can be skipped if you just want to buy ore, but for me I had a stack of forest emeralds etc which I have been transmuting since 3.2 came out, makes me 150 + g every day for 2 minutes work.
Tailoring might be worth it to make the most inexpensive blue item you can make and then use an enchanter to DE into a shard. Bags are the only thing I normally can sell easily and the prices of bags have dropped a lot. The only thing about tailoring is that a lot of frostweave drops in dugeons and so it is a very passive money maker.
