Not sure what type of camera you have, but a typical home video camera does not have the proper quality for television. Most cameras used by the professional hunters average around $5,000. I've done some research on this myself, I think the best approach to take would be to try to become a "team member" of one of the big outfits, like realtree, Drury, etc. You would then submit your material to them and they would pay you.

I think it would be very difficult to break into the market on your own, point is most people buy vidoes from the reputable pros, not joe blow.
