You can try selling mats from Esoterics. Go for the NQ items as they are only 20 Esoterics and don't sell for much less than the HQ ones. Of course, it depends how much they sell on your server.

On mine, they go for about 40k a pop and with your dailies, you can get around 250 Esoterics a couple of roulettes. So possible up to 500k (minus the tax so maybe less) in mats if you can part with your tomes.

As a crafter, I buy these mats regularly to make 220 gear.
