You don't have to have a lot of money to do lighting. Screens made out of bed sheets work for diffusing light (which at 8:00 is prolly not needed), reflectors can done out of most anything. Just a matter of perception on their end as to what makes them want to pose or run and hide. They already want you there, so they have your trust. All you need to do is not fail, that's all Can't wait for the pros to start talking. I'm getting excited for ya. Once you do a couple of shots on a stand-in and get the exposure close, you'll eat it up. Might be harder keeping up with the setting sun if you stick with ambient though.
