Watch the calendar.
Try to shoot between May and September. The days are longer, the weather better and even if the shoot is indoors, the light coming through the windows makes a big difference (everyone looks better, too!).

You'll get more hours per shooting pound if you can plan your production within this timeframe.

Beware the really cheap quote.
Lots of people can 'use' a video camera these days and anyone with a PC can 'edit.' However, neither of these facts turns someone into an outstanding filmmaker or a talented editor.

Cheap videos tend to look that way and have a very short shelf life. Outstanding videos bear the test of time and will give you the best possible payback. A good video is one you're still proud to be screening five years.
