Need eng. guideFollow

Currently I have 225 mining, and about 250 LW. I had eng. before, and cahged ot LW for money, but now I realize eng. will benefit me and guild better. I dont have much money, about 30g atm, but am willing to spend lots on power leveling eng. I just need an eng. guide if thats not too much to ask for.

How do you use leatherworking for money?.... cept deviate scale belt (with skinning), and the heavy armor kits when dmf comes along. With engineering. you can sell deadly blunderbuss for 1g on ah. it's for the warsong supplies quest. ps. if you've one equipped and you're passing the second one you just bought on ah to the girl, equip the one you don't want first. she'll take the blunderbuss off your equip before she takes out of your inventory.
