The time frame isn't too rigid or anything. Pretty much from now until 2.0 get released. Factions that I've done are these: Arverni, Belgae, Parthia, Seleucids, Ptolemies, and I'm slowly dredging up info on Pontus right now...they're quite difficult . The third Celtic faction I will do them. Keravnos has done Sparta's unit descriptions and with help get Macedon done along with help from the fuzz.
Faction that need to be done are these: Scythia, Sarmatia, Dacia, a Germanic faction, Pergamon, Armenia, Carthage, the Iberian tribe, and Rome that will need some love (I think I got everybody). You'll work the historians on the team to get things done. Look at the previews for Sparta and the Belgae. We aim for that level of info if possible. We want to inform the player on the unit's history, its famous commanders, what they did in real life, what happened in battles they were involved in, etc... If you think you can help then sent a PM DvK or tone
