I have 8 inexpensive simple 5x7 frames (I think they were from IKEA) along the wall above my TV.
3-4 times a year I change them out, using photo paper in my cheap home printer. I use 8.5x11 paper, 2 to a sheet, and cut to fit the frames. I get a lot of compliments on the display.
I also have a screen saver on my small kitchen TV of my all time favorites.
Non model models and real food is definitely 2 issues that can torpedo a shoot by themselves.
Get there early, check lighting and backgrounds for future reference.
Make a point of getting pictures of young guests with or without their parents as soon as they get there, especially the littles. This way, you'll have pictures of them without cake in their hair, which their parents will appreciate, and possibly remember you when they need a photographer.
A loud squeaky toy can be a great aid to getting little kids to look at you for a photo. Works great with pets as well.
I started in the '70s, as a broke teenager shooting film, so I've still got the habit of being stingy with my shutter button.
For 'live' circumstances where I have little control over what's in front of the camera like sports, I usually get about one keeper for 10 clicks. With a little more control or a planned event, like a wedding, I might get 3-4 keepers out of 10. In studio, with a model, I might get better than 5 out of 10.
Ship it.
