'Artificer' character optimisation

[Resistance]

I'm not referring to the third party or 3.5e artificer, I'm looking to create a character that's optimised when creating magical items (specifically constructs) so that they can be made as quickly and as cheaply as possible.

I don't mind how weak this character is, it can be a commoner for all I care. I just want to get the most efficiency out of crafting.

http://www.d20pfsrd.com/traits/magic-traits/eldritch-smith (this applies to metals, so all metallic constructs. Requires you to be a dwarf)
http://www.d20pfsrd.com/traits/magic-traits/hedge-magician (lowers magical items by 5%)

Now, I'm not sure if they'll stack. I do assume so.

Then, to lower the time of crafting I can take forgemaster
http://www.d20pfsrd.com/races/core-races/dwarf/forgemaster-cleric-dwarf

A dwarf cleric archetype that can craft magical items in half the normal amount of time.

The character I'm creating is level 9, so far it should be:
Forgemaster 5 then I will multiclass with something else for efficiency.

I will also ask if I can swap out ability scores (like strength, charisma, wisdom, dexterity which I'm not going to need) for price reductions for magical items (1% per ability score) it's 25 point buy.

I direct you to this, an Arcane Discovery that can be picked up by a wizard.

I also suggest not multiclassing, whatever you do. Your caster level takes a big hit when you multiclass, meaning you can't make the higher level items, and it takes much longer to get the higher level item creation feats, like forge ring or craft staff.

I can take magical knack to help adjust better.

Wizard discovery is fantastic, I can now make things at 75% the time! It's definitely worth a one level dip into wizard.

There's another thing that's wrong, with Eldritch Smith and Hedge Magician. Both of these are Magic traits, meaning that you can't take both. This is before you take take into account Magical Knack, which is also a Magic trait.

I would actually recommend a dwarf wizard over a forgemaster. Have you checked out the dwarf wizard favored class bonus? It's rather amazing for crafters.

There isn't a dwarf favoured class bonus for wizard?

From the advanced race guide under dwarf fav class options:

Wizard: Select one item creation feat known by the wizard. Whenever he crafts an item using that feat, the amount of progress he makes in an 8-hour period increases by 200 gp (50 gp if crafting while adventuring). This does not reduce the cost of the item; it just increases the rate at which the item is crafted.

Its pretty salty, i would consider 5th level forgemaster as well though.. free metamagics and half-time crafting metal is really nice if your looking towards constructs.. Along with the construct discovery of 9th level wizard i could a 15th level guy making iron golems really fast lol..
