I will echo the sentiment of using handbook material for the Factotum as a substitute for an Expert class Handbook as the SRD core Expert is basically a stripped-down Factotum:

• They have a weaker HD (d6 vs the Factotum's d8) due to being a NPC class vs the fully playable Factotum
• They get a roughly similar skill point allocation (6 pts/level, x4 at first level); however, they are only allowed to pick ten skills as class skills, vs Factotums which are allowed to take everything as class skills.
• Experts get their strongest saving throw progression (and it is a full-strength one) in their Will save, which is slightly odd because the class is intended to be low-tier for statting NPCs; Factotums, on the other hand, get a strong Reflex save, consistent with them being roguelike, finesse fighters.
• The BAB progression between the two classes is identical -- they both get Rogue BAB, in other words.
• Experts lack the martial weapon and shield proficiencies granted to Factotums -- this is in line with them being a NPC class, but does mildly hamper them in combat (it renders them incapable of using trip weapons)
• Experts have no spells or class features, of course -- Factotums could be said to be a half-caster class thanks to Arcane Dilettante, and have a significant class feature set, which allows them to be SAD (Single Attribute Dependent) on INT for the most part.

This means that you can pick whatever race fits the skills you want, and can skip the sections of the Factotum handbook that deal with class features and progression, as well as ignoring the one Factotum-specific feat, Font of Inspiration. Many of the other Factotum feats, skills, and skill tricks are useful for Experts as well, though -- you may even be able to apply traits or flaws usefully in your Expert build.

One unfortunate part about the Expert is your weapon selection is severely limited; daggers, gauntlets, slings, light crossbows, and perhaps staves are your only real options as pretty much all the other weapons that are truly interesting to Factotums are martial or exotic. However, you should pay close attention to the Factotum handbook's suggestions regarding utility and magic items, though -- both Factotums and Experts can get access to Use Magic Device as a class skill, of course, and utility items can boost those all-important skill checks. Furthermore, being a non-caster makes your UMD that much more important (a Factotum without anything to use UMD on can still do some stuff with Arcane Dilettante and Opportunistic Piety, while the Expert is just like the Rogue in being completely UMD-dependent for their magic tricks).
