I've noticed a rather large hole in the enchanting rules so I'd like to suggest an alternative archetype to fill that gap.
(Wizard Archetype)
The Artifacter is a true master at creation, specifically working with magical items. An Artifacter can turn out a wide variety of magical items and can function in party in the same
role as a normal wizard.
Restrictions: Must select arcane bond, must select four opposition schools.
Consumption: At third level, the Artifacter may destroy existing magical items to capture a
portion of their power for enchanting a new magical item. He recovers 15% of the value from
a single item when using this ability.
At 6th level, he recovers 30% of the value and can consume two items.
At 9th level, he recovers 45% of the value and can consume three items.
At 10th level, he may destroy one cursed item with no ill effects. This must be done as
a stand alone (i.e. not part of item creation)
At 12th level, he recovers 60% of the value and can consume four items.
At 15th level, he recovers 75% of the value and can consume five items.
At 18th level, he recovers 90% of the value and can consume six items.
Nothing Up My Sleeve: At fourth level, the Artifacter can use a spell that he doesn't know as
long as he possesses a copy of the spell in creation of an item. He must otherwise be able
to cast the spell (see Use Magic Device).
Smithy: At fifth level, the Artifacter gains Craft Armor and Weapons feat. For the purposes of
this feat, his caster level is double his Artifacter level. This ability replaces wizard bonus
feats.
Fast Enchanting: At sixth level, the Artifacter makes magical items faster. He now creates
items at the rate of 2000 gps per 8 hours of work, with the appropriate increase in potions and
scrolls (as per Magic Item Creation, page 549). This increase to 3000 gps per 8 hours of
work at twelfth level and 4000 gps per 8 hours at eighteenth level.
