My videos take a SOLID three weeks to create. There is no money spent, per-say but I have invested QUITE a bit in equipment, such as a teleprompter rig, lights, ect. I have just now started testing with advertising my videos just to get a sense of how it works for future knowledge, so there is $30 so far ever spent in ads.
My camera gear, which I have accumulated over some time, is probably at this moment worth somewhere around$700-$800, of course, the camera alone cost about that much when I originally bought it -.-
