I'm currently gaining a PhD in medieval and early modern history. I'm not sure how much I could help with subjects of antiquity and the classical age. I do, however, have access to a fine university library here in the UK. If there's a particular book someone needs a quote from, I suppose I could be your go-to guy for that. I'm doing tons of research at the moment, but I'm usually in the library anyways, so feel free to name a source you think would be helpful and I'll look it up.

For example, my library currently holds the following book that sounds entirely useful for province descriptions:
Hammond, Nicholas G. L. (ed),
Atlas of the Greek and Roman world in antiquity (Park Ridge, N.J.: Noyes Press, 1981).
