Not sure why you are broke. Are you not looting in your instances? With my group, I went from SFK to SM to Sunken Temple to Scholo. When they hit 60, I had 10K in gold from just selling the cloths and the rare+ items that I had disenchanted. By the time I hit 70, I should have enough to buy each of them their epic flyers at this rate. Make sure you are looting and buy as many bag for your alts as you can. Load them up, head to AH and sell the crap by the bagloads. If you aren't making a crap ton of cash, something is very wrong.
