As someone who has tried and failed to launch a "self-distribution" platform, there are only so many things you can do.
1) Don't rely on film makers finding you. You need to heavily curate content and launch with a large, and respected, library. This means venture capital or acquisitions and marketing.
The issue there is finding content worth watching... who aren't already good enough to get great distro deals. You get stuck with B or C level content and who wants to become loyal to a site like that?
2) You're competing against Film Annex, Youtube, Vimeo and so on in terms of sites with low barrier to payment. Deals with Netflix, Hulu and iTunes are walled gardens, but understand their pricing. If you don't already have some experience in distribution either online or in the real world (theatrical, VOD, cruise ships, airlines, hotels) then I wouldn't rely solely on technology to launch a company unless it's game changing.
3) You'll need a good amount of first and second tier advertisers for most business schemes.
Jaded? Maybe, but I learned a lot in the process of my failure. Unless you're coming in as a split-off from a tech or distribution company that understands media well and with a full team, I don't have high hopes.
