Let me tell you a little bit about what I do. I am a photographer and video editor involved with stock photography, web advertising and video production. I have many third party clients looking for different types of media and I sometimes hire models to help me meet their requirements.
The theme for my current client work is along the lines of "Honey I Shrunk The Kids". My client is looking for short scenes in a POV or "point of view" style film where the camera would be portraying a shrunken person. You would be portraying a regular sized person.
They are looking for a few different scenes where the tiny person is avoiding getting killed. I.e. avoiding people walking. Or sometimes actually being killed. There was a scene in the original movie where one of the shrunken characters almost got eaten and they are looking for something along those lines too.
If you're interested please feel free to ask questions. Previous modeling experience is not required.
