A spell that makes creatures.

[jaker2003]

Ok, I'm looking for help with the spell level and any part of the spell description i didn't think of.
Here's the spell:
Armored Servant
Conjuration
Level: Sor/Wiz 5?
Components: V,S,M
Casting Time: 10 minutes
Range: Touch
Effect: One mindless construct.
Duration: Permanent
Saving Throw: None
Spell Resistance: No

This spell fills a suit of full plate armor with the conjured essence of a mindless servant. The spell creates one armored automaton, suitable for guard duty or simple tasks. A single spell of 4th level or lower can be attached permanently to the automaton. This spell must have a non-instantaneous duration and a range of close or less. This second spell is cast at the same time as the armored servant spell, and its casting time is subsumed into the 10 minute casting time for this spell.
Material Component: suit of full plate armor (worth at least 1500gp).
Here's the construct it creates:
[sblock=Armored Servant] Armored Automaton
Medium Construct
HD: 8d10+20 (68 hp)
Initiative: +2.
Speed: 30 ft.
AC: 20 (+2 Dex, +8 natural).
Base Attack/Grapple: +6/+12.
Attack: Slam +6melee 1d6+6
Full Attack: Slam +6/+1 melee 1d6+6.
Space/Reach: 5ft./5ft.
Special Attacks: Permanent Spell
Special Qualities: Construct Traits, DR 10/magic, Repair, Magic Vulnerability
Saves: Fort +2, Ref +4, Will +2
Abilities: Str 22, Dex 14, Con -, Int -, Wis 10, Cha 1

Environment:
Organization: Solitary
CR: ?
Treasure: None (that’s right, you can’t get the armor back)
Alignment: Neutral
Advancement: None

This suit of armor stands at just under eight feet tall. The helm turns, as if an invisible wearer is watching you.

COMBAT
Armored automatons do as they are instructed by their creator, understanding any verbal commands.
Construct Traits (Ex): Low-light vision, Darkvision 60 ft., Immune to all mind-affecting effects, poison, sleep effects, paralysis, stunning, disease, death effects, and necromancy effects; cannot be healed, immune to critical hits, nonlethal damage, ability damage, ability drain, fatigue, exhaustion, or energy drain; immune to any effect that requires a Fortitude save (unless that effect also works on objects, or is harmless); Immune to death from massive damage, and cannot be raised or resurrected.
Permanent Spell (Su): An armored automaton can continuously gain the benefit of any one spell casted into it. This spell is extended to a permanent duration, lasting as long as the armored automaton it is attached to. The spell attached must meet the following criteria: it must be of spell level 4 or lower, have a range of close or less, and have a non-instantaneous duration. The spell functions as if the armored automaton had cast it on itself (CL8), even if the creator is of a higher level.
Repair (Ex): An armored automaton heals up to 8 points of damage over the course of a day (1 point every 3 hours).
Magic Vulnerability (Ex): An armored Automaton is created by the armored servant spell, is vulnerable to effects that disrupt magic. If exposed to an antimagic field, the armored automaton collapses into a pile of inanimate armor, until it is removed from the field. An armored automaton can be destroyed outright by a successful dispel magic check. The armored construct adds its 8 Hit Dice to its creator’s Caster Level check.[/sblock]

1) It's far too strong a construct to get for free with a 5th level spell.

2) You need to define the "Permanent Spell" ability better. It should be a non-instantaneous spell that targets a creature and exclude 'Range: Personal'. Attaching a permanent Black Tentacles to it would just be wrong. Another good step would be to note that only spells that can be made permanent with Permancency are eligible.

3) Once you've more clearly defined the "Permanent Spell" ability, you should add an XP component of 500xp/Spell Level for the permanent spell.

4) What warrants the huge resistance to Dispel checks? From a high-level caster it becomes near un-dispellable.

5) Instead of DR it should just get Hardness equal to the hardness of the targeted armor.

6) Along those lines, I'd probably just set it's HP to that of the targeted armor as well.

7) The more I think about this, the more I think it should just create a size Medium Animated Object

8) In fact, your mage should probably just research a Sor/Wiz version of Animate Objects or replicate it's functionality via Limited Wish

It pains me to say this, because I hate their existence conceptually, but you need an XP component for this spell badly, or else it will be abused. I would recommend one for the spell, and another based on the spell level of the kicker spell.

Edit: On top of what Pyrex said, this should be instantaneous.

Yeah, if you wanted your spell to function as-written, I'd say you need to change the duration from Permanant/Instantaneous to 1 min/lev.
