Nice points. Can't overstate the value of good lighting - that's they key to making a simple video look professional. All you need is sunlight (if indoors, aim for the brightest time of day, but if outdoors avoid noontime because it creates some awful top-down shadows) and a reflector to bounce the sunlight to the other side of your filmed subject.

Reflectors are cheap ($20+) but sneaky tip is that a big piece of white foamcore is almost as good.
