Trajan Regular

Please recommend a font similar to Trajan Regular but in Word or iWork (or free)?

I need to self-print two emergency envelopes for invitations that should have gone out last week (all the others did already). My invitation typeface is Trajan Regular. Is there a typeface that is sufficiently similar but available in either MS Word for Mac or in Apple iWork? I'm really in a jam and I can't afford the turn-around time involved in getting my envelope person to address them and return them to me. Thanks!
