Does anyone know where I can find good cheap lighting tools? Always when we film inside the film looks grainy, and I think extra lighting could help that.

Lighting will definately help.
I don't know of any cheap lighting tools. Not many out there that are of quality.
I know that Dedo lights are one of the best, but very expensive.

Im in a hurry but... do a search on the forum for cheap lighting and you can find a whole bunch of ideas all over. I woudl look for you and im in a hurry and ur just being lazy! haha hope you find what your looking for

You could use those drop lights and umbrellas. Or you could buy some industrial type lights from any hardware store and use umbrellas (maybe one painted white/or just a white umbrella if those exist, and one black umbrella) to reflect the light. And I would suggest maybe putting wax paper over the lights to keep it from blazing.

You can do a lot with cheap stuff actually. Just be creative and imaginative. Use your mind!

durden is right i found some gnarley work lights at big lots for $25. Killer eh? Cover a piece of foam core with tin foil for some good fill.

I just did a bunch of interviews with some demolition derby drivers...it was night and we were standing between a barn and the arena. There was a little light spilling over from the arena, but I brought out my new el cheapo $80 Bescor on-camera light for the first time...the results are great! I was worried the subjects would be white blobs, so I only used one of the two 20watt bulbs...but they look fine! Very natural-looking skin tones, except when I accidentally got up too close.
