Share 'I need an Ambulance for my film.'

I'm making a short/ feature and the company I was going to get an ambulance from for free just informed me that they totaled the only other one they have.  So now I need help with this.  Please email me any source possible to help out.  I don't have much to offer other than credit and a copy of the vehicle in service.  Maybe a simple Commercial in HD for free.
