I just did an outdoor short. We used a lot of utility extention cable and a lamp from wal-mart. That worked out perfectly for us. I dont know how close you are to a power soure but that may work for you. If no power is availible, (depending on what you're editing with) try shooting during the day any mask out a little light or tone it down in post.

Now that's a difficult problem.

The best quality lighting comes from lights. If you can't get lights
to the location I have no idea how you can get the best lighting.

It looks like you're kinda stick with the old "day for night" trick
like Shaolin suggests. But that's quite a challenge - get the
best quality lighting using no lights....

Any ideas anyone?

I'd shoot during the day. The trees will block enough light to make early evening seem credible.

You might also consider bounce-boards as they are cheap and require no power or sound and can reflect light to soften shadows and brighten faces. You can use straight white foam board or cover a board with aluminum foil.

I second rjschwarz's suggestion of using bounce boards. Try and shoot in the late afternoon on an overcast day--the light will be softer and look more like moonlight. You should also underexpose by about a half a stop. Then in post you can bring out the deep blues and darken it further, depending on the look you want.
