Hey, that's super-helpful for what sounds to me like an interior location. (Or outdoors at night?)
Freddy, there's not much you can do on $0 budget unless you already have some tools at your expense. Do you have any inventory of work lights or other tools you think might let you improvise?
While not ideal, and it may require some purchasing, you might look at halogen worklights from the home improvement store. They're bright, with the challenges being that they run very hot (cool before touching) and they're more difficult to control because they are floods. BUT, depending on the location, you can bounce them.
Can you tell us a little more about the location? Indoors? Rough size? Color of walls and ceiling?
You can use white walls and ceiling as a bounce, or you can use white foam core (science fair project poster board) to bounce and black foam core to cut. Just don't put any paper products too close to the lights.
If you can find room in the budget, order a roll of black wrap from FilmTools or B&H. It's basically aluminum foil that's been black-anodized. You can wrap it around the lights and use it to shape and cut the output.
These aren't great lights, so don't expect award-winning lighting, but they can do in a pinch.
