I think that you guys are getting a bit irational, you knwo proffesions are not the only way to get money. There is something called farming, Go to SM, get a buddy, and go through an instance abuot 5 times, you get about 10g right there, you get maybe 2.5 - 5g from money drops, and about another 5g If you sell the items on AH that you get from farming SM.
Tailoring is invaluable to you, since you are a mage, especially in later levels, It will save you loads of money, since buying form AH will only get you into a big momentum of money spending, never a good idea, and anyway, its esier to farm the items, and make them, then you can disenchant, especially since robe of power has a good disenchant item, and its BoP, which means you can't buy it.
Also ,enchanting is a great skill, but face it, until you reach lvl 270+, you aren't going to make any real money, it is a money sink, but if you buy icy chill, and sell it, you can get abuot 60g each sell!!! and that applies to most 300 nchanting.
All in all, tailoring/enchanting are the hardest skills to have, but they are the best skills at the end of the day, and they make loads of money when properly used to gether.
My advice Is to just hang in there, and to go farm some instances if you need money. Good luck :)
