basically, your replace your gear way too quickly, each level or 5 you should replace your weapons and gear. from drops, quests and instancing. only really enchant your gear, if it's really cheap (fiery is a nice leveling weapon enchant) or your gonna keep that specific piece of gear for a long time (ie level 70)
i'm lvl 43 main warr and 296 ench i think it is. if you do them your self not that bad. i buy stuff lvl 41+ for 1.5g or bid on them i have some peeps who cod me stuff they use to lvl up they're trade skills. use the mats you need to skill up and sell the rest. i've been able to keep makeing alittle gold each week except on weeknds when prices of mats go down alot. also there is a great guide on how to lvl up to 250 on thottbot.com if you go there mouse over profsions then click enchanting then when it loads click coments about half way down there is a big yellow post that tells wich enchants to do and how long to do them from 1-250.
