I have a [Kodak Easyshare z950](http://reviews.cnet.com/digital-cameras/kodak-easyshare-z950-black/4505-6501_7-33765257.html) camera. Previously I only used it to take some pictures while traveling. Now I want to seriously work with video. Not that seriously as in TV studio, but still I want to produce high quality videos.

It shoots HD720p which is pretty good. While I'm outside it looks well, but if I shoot inside, the footage I produce is grainy with lots of background noise.

I think if I installed some proper illumination it would be fine. The problem is my budget is very limited something around $50-$100. How do you get the most lighting with least amount of money? I thought about just buying the most powerful light bulbs in the store and using some aluminum foil as a reflectors. Any better ideas?

I also thought about waiting for spring and when it's at least 10°C I could shoot outside. Problem then would be the sound, because wind blows into the mic. Should I build some hard cardboard walls or something?
