Not the Bradys - XXX (2007)

Synopsis

A family that greatly resembles the Brady Bunch but apparently isn't is having financial troubles and may have to sell the house. Therefore, the children (three boys from father's first marriage, three girls from mother's first husband) decide to get jobs without telling their parents. Eldest daughter Marcia applies for a job as model, youngest son Bobby starts helping Sam the Butcher in his shop and the girls start a car-washing service.
