Hmm i think, to be honest, you would probably be better off doing the shoot yourself, purely from a cost analysis basis youll be saving yourself a heap of $$$.

Another alternate would be to do a full shoot and make sure that towards the start or end of the shoot the models to what you want them to before getting into the actual 'shoot' itself.

Good luck and if you do find someone who is able to do smaller clips for you please let us know who
