Why would they? Tonight I spent an hour setting up 3 lights, taking test videos, uploading them to my computer, watching them and then making adjustments, etc.. all to make one 12min custom vid. Now it's gna take me another 30mins to upload it, edit it then email it to the guy. That's a LOT of work for a little 12min video. The same amount of work would go into an hour long video or a 2min "fansign" vid like this one.
People aren't aware of all of the behind the scenes stuff that goes on to create a video that looks simple and effortless, and that's prob a good thing, they're not meant to. But my point is, nobody likes to work for free.
Now if you were a member of my website or bought me a present or supported me in SOME sort of a way I would be more inclined than just some random dude on a random forum asking for a handout, just because he wants one..
