Hit Kolskeggr and Saunarach mines for gold/silver if you don't want to transmute. I agree with ShadowGambit on Jewelry and Dwarven Bows, or Steel Plate armor for left side. After the patch, they have given Iron daggers a diminishing return on value, so this number will be much higher. Before the 1.5 smithing patch, it took 570 Iron daggers without warrior stone and without a sleeping bonus to go from 15 to 100 smithing. If you are going up the left side of the tree, Steel Plate Armor is the best thing to do if you don't take the Dwarven Smithing perk.
