Ah.....ok, so I got that bit wrong then. Apologies for misreading your affiliations. Just as well 461 isn't here to cane me for my fallibility.
There are many excellent books that beileve as you do, and possibly the best is Alexander Reese's The Approaching Advent of Christ. It's a classic in its field, and quite possibly out of print at the moment.
It might be available on-line (I haven't checked), but since you don't have a lot of time for personal study anyway, somewhat academic.
