I used to enjoy weddings.
I'd shoot them on film (120 and square format). My clients would pay 1/2 up front, with the other 1/2 due with the instructions as to what was to be included in the package price album.
I'd shoot about 8-10 rolls of 12 exposure 120 for most weddings.
I had my lab develop and do 5" x 5" proofs.
I would take the proofs, label them with roll and negative numbers and edit out any obvious culls. I would then deliver them to the newly married couple along with instructions about what I needed to make up the album they had agreed to buy, as well as order sheets for extra enlargements which could easily be shared with friends and relatives.
Typically, the newly married couple would have the proofs in hand about two weeks after the wedding.
For an extra fee they were entitled to buy all or some of the proofs. My lab did a great job on the proofs, so they would often sell.
My albums were expandable. I frequently had people decide afterwards to buy more enlargements and expand the size of the album.
Once people decided (with my help) which photos were to be included in their album, I would usually have the completed album back to them in 2-3 weeks.
I never discouraged other people at the wedding from taking their own photos. I frequently saw their results. I still sold extra prints, at a decent profit.
