I need some High Definition videos of landscapes (you say me before how many videos you are willing to offer for my budget) with heaven and clouds, without people passing or showing (I will use them as background for presentations), it is good if sometimes birds cross the landscape (do not worry about birds), it is good in the videos to see the trees being moved by the wind, to see the sea, the clouds, etc. You must let quiet the camera to film the landscape. Perhaps 15 minutes per video is enough, but If you like extend for 30 minutes it is very good. Obviously you must write to me a lifetime permission to exclusively use them in whatever production (comercial or not comercial) I want. Thanks.
