If you have a twink caster you are probably going to stay at that level for quite while. If you level your engineering up to the point where you can wear the best googles you can get, put them on, then drop engineering, the googles will stay on you until you take them off. So you could then pick up a different skill.

If that doesn't work and you need gold quick, I recommend The MMORPG Exchange WoW Gold. They deliver quickly and are cheap! I usually receive my gold within 20 minutes. They're my secret weapon, I highly recommend them!
