For 3.5e, there are a couple of different ways (Especially since you say a bit of cheese, for that I am going to borrow a little from other systems/homebrew).
From the Eberron Campaign Setting (Pages 52, 53 and 56) there are three feats, Exceptional (Reduces time), Extraordinary (reduces cost) and Legendary (reduces XP) Artisan, the texts are as follows:
EXCEPTIONAL ARTISAN
[ITEM CREATION]
You are an expert at creating magic items faster than usual
Prerequisites: Any item creation feat.
Benefit: When determining the time you need to craft any item, reduce the base time by 25%
EXTRAORDINARY ARTISAN
[ITEM CREATION]
You are an expert at creating magic items at a lower cost than usual.
Prerequisite: Any item creation feat.
Benefit: When determining the gold piece cost in raw materials you
need to craft any item, reduce the base price by 25%
LEGENDARY ARTISAN
[ITEM CREATION]
You have mastered the method of creating magic items.
Prerequisite: Any item creation feat.
Benefit: When determining your XP cost for creating any magic item,
reduce the base cost by 25%
That's what I found from official sources. Now for some of the cheese, including borrowing from other rulesets and a homebrew item.
If you borrow from Pathfinder, there is a general feat called Cooperative Crafting, which allows you to speed up crafting with the help of an assistant:
Cooperative Crafting Your assistance makes item crafting far more efficient.
Prerequisites: 1 rank in any Craft skill, any item creation feat.
Benefit: You can assist another character in crafting mundane and
magical items. You must both possess the relevant Craft skill or item
creation feat, but either one of you can fulfill any other
prerequisites for crafting the item. You provide a +2 circumstance
bonus on any Craft or Spellcraft checks related to making an item, and
your assistance doubles the gp value of items that can be crafted each
day.
I did also run across a homebrew item, Fast Item Creation, which adds to the GP value that can be created in a day, reduces the time, and stacks with itself (No opinion given on how much it can break things):
Fast Item Creation [Magical] Spellcasters can create items faster.
Prerequisite: Ability to cast 4th level spells
Benefit: You increase the daily rate at which you create magical items by 1000 gp.
Normal: All spellcasters normally create items at the rate of 1000 gp per day.
Special: This feat can be taken several times, and stacks with itself.
Each time it is chosen, add 1000 gp to the value of a single magical item that the character can create per day. Thus, items take half the usual time to create with one feat's worth of Fast Item Creation, one-third the usual time with two, and so on. A minimum of one day is still required for the creation of any item, however. In campaigns using Psionics this feat can also be used to speed up the creation of psionic items, for those that meet an alternative (or additional) prerequisite of the ability to manifest 4th level powers.
