Help!!!!!!

Does anyone know any insurance companies or places that sell insurance in Vic for reasonable rates? I am trying to set up a small professional theatre company and need to find insurance thats affordable, for performers and tech, and that will let us do TIE.
Help me, I can't seem to be able to find anything other than ITA (who I might add, if any of their admin. people might be reading, have not gotten back to me with any details after several emails) and Duck for Cover. If anyone has suggestions of where to look, who to ask, or companies I should try, I would be very very grateful.
Thanks
Naomi
