Simple, get auctioneer, get some starting gold (farm/dailies) and scan for stuff to disenchant.
There are enough guides in how to do that, youtube has some.
Buy gear that gives 5/10g profit when disenchant, buy, disenchant, sell.

Certain old enchants, 15 agi, minor run speed, stats chest, crusader, mongoose, sp wep are still very viable and mats are easy to get by.

GL!
