Digital BW, The Print

I have a project where I need to produce three archival albums of photos of
various Benedictine monasteries.  There will be about 30-40 prints per
album.  I was going to print on letter-size HM PR 308, but I have little
information on how to assemble into an album.  The only choices I see are
(1) to have the prints bound into an album some way or (2) to have the
prints loose in an archival box with interleaf sheets.  Light Impressions
purports to have an album kit that can be bound, and I have an email in to
find out what the matte paper is.  Binding into an album seems attractive.
Cost is not a consideration within reason (reason meaning I would like to
keep the costs of binding and the album covers to about $150 each or
less...).   Most of the prints will be max 6x9, so I thought letter size
might work well.  Any experience, thoughts or advice very welcome!
