You can also try an speculate in buying fx. cloth, then tailor stuff, DE it and sell the Mats on AH.

You can find items which gives a fair margin.

For me, all crafted items ends up being DE in the end.

Tailor - Cloth to Item - Item gets DE
Leather - Leather to item - Item gets DE

When I level the above professions I always make stuff I can DE. Always!
And my Enchanting is the last ability I level - Always.

I usually lvl my professions all at once. It's usually when my guild bank gets to crowded.
