Welcome to the Phase II boards. I am just a boardie, and I do not speak for Phase II, but I think I know the answers to your questions. Phase II, as you probably realize if you've watched their episodes, is far closer to TOS than most fan films... which means that the copyright holder watches them like a hawk. Kickstarter, therefore, is not an option... CBS and Paramount have spoken.
That said, welcome. These are GREAT people and they produce a great fan film. As far as number of viewers, I believe (again, I'm at best a secondary source, somebody who knows more than me will be by later) ... that Phase II has had over 100 million views and downloads. So I don't think there is an audience problem!
