This post is probably after the mentioned wedding but I did not want to leave the comments of lopman24 and apushatayid uncostested.
A normal mitzvah tanz,where mainly family and close freinds stay, only requires a badchan for an extra hour or so. The main band has usually left at this time and only a skeleton musician is there for music. The hall-obviously- you need for the wedding , so there is no extra expense there.
Only at so-called “rebbeshe’ weddings do you have extensive mitzvah tenz and this is not what is asked for anyone else.
