The Mainstreeters initiated a number of commercial enterprises. Support Modelling was a modelling agency comprised of members of the local art and punk rock scene. To promote the project, Paul Wong made a three-channel video (later adapted to single channel) that featured certain Mainstreeters in various states of undress, accompanied by a disco soundtrack. Support Modelling also appears as a series of concept ads (weddings, funerals) in Ennui magazine.
