Honestly, xmutes alone could keep most 5-boxers in the money to the tune of 1-2K/day. I currently have 6 Alchemists (6-8 epic gems/day), 2 Miners (Titansteel) and 2 Tailors (Moonshroud/Spellweave/Ebonweave). Toss in 4 Jewelcrafters spending 15 mins on the daily which adds gold and Dragon's Eyes, and that's an easy way to keep a steady income.

Skilling up is a bit of a pain, but well worth it after the second or third week of watching your net worth grow steadily. Most of the professions can either be bought or farmed without too much trouble, especially Tailoring. No excuse to not have at least a few Tailors doing a bunch of xmutes.
