Vintage Tea Cup Sets

Hi! So my wedding will be vintage themed and I am looking to order sets of porcelain tea cups, pots, and sugar bowls. I will use the tea pot as my bridal shower centerpiece and display fresh flowers in it (play a game and have one person per table win it). Then I will give out tea cups to each person as a bridal shower favor. The sugar bowls will be the wedding favors. I am looking to have mix and match sets so that the guests can have unique collections. I will also be having 250-300 guests so I am trying to keep prices as low as possible. Does anyone know where I can buy something like this in bulk/for cheap?
