Consider your budget before you invest in any video equipment.  There is one principle that we live by here at Fairfax Video Studio: No Random Acts of Marketing!  Before you try to do your own videos, take into account the costs of other things like lights, editing software and microphones.  Then consider the time it will take away from your real work.  We recommend that you hand the project over to an expert.  Let us focus on creating awesome videos and you concentrate on running your business.
