DIY Photo booth items (Capitol Hill near Lovejoy Park)

A friend is assembling a DIY photo booth for her fiancé's birthday - does anyone have supplies for this that they are not using? Happy to pick up! Party is this Saturday. I think she is specifically looking for a light camera that allows you to put your iPad on it and something that holds up a backdrop and a backdrop. The party theme is casino night. She's open to other supplies - printers, polaroids, etc. Thanks for considering!
