as for me..to get my crafting this high i have been making orbed battle staffs and high alching making anywhere from 8k to 9300 gp per staff depending if i buy runes, seaweed, or orbs or i make them myself. this gives me crafting, magic, runecrafting xp for each staff also..just dont go to thorac to change them into mystic battlestaffs or you loose 30k gold
