I think I have a couple resources you could send him to try:
There's a website called StageAgent, I haven't used it before, but it looks fairly simple to single out songs based on your range and provides easy ways to listen to and purchase the music:
http://www.stageagent.com/browse/auditionSongs/baritone If he uses this, I'd be really interested in learning if it was a legitimate resource with good suggestions.
There are the 16-Bar Theatre Audition Books in several different ranges. Here's a link to the one for Baritone:
https://cv.schooltheatre.org/cgi-bin/msascartdll.dll/ProductInfo?productcd=450491 The Singer's Musical Anthrology (also comes in various editions):
http://www.sheetmusicplus.com/title/the-singer-s-musical-theatre-anthology-volume-3-baritone-bass-book-only-sheet-music/3563748 He could also try researching baritone roles in musicals and then looking at the musical to see what songs they sing. I hope that helps! Tell him to pass along any other resources he finds!
