I think you may be disappointed with low quality scans and getting someone else to do the layout.
Even this weekend my Mum had my Dad’s book out looking at it. It is a great memento to have long after the cake and party are over and the time and effort over the layout and selection of photos was well worth it. Although my sister spent months on the photos and layout with me I get all the kudos because I sent it off to the printers!.
I found it was about €50-60 for the book and I will definitely be checking out some of the other recommendations here, having the photos printed out is brilliant.
