I'm not asking for hundreds of thousands of dollars. I'm reasonable in my rewards, my pricing, and my funding amount.
My last 3 campaigns were for $2500 (raised 10,000), $3000 (raised ~$5700), and my current one is for $5000 and I'm currently at ~$6300.
The best thing I have found is to just keep people in the loop. Even if nothing has changed, I make an update every week to let the backers know I'm still around.

I don't think social skills matter as much as those.
Ed:
I may have phrased it snarkishly, but that's honest advice -- if you're not good on camera, find a film student to help direct brief bits you're in (so you perform better, are framed well, etc) and get other students to do most of the on camera work.
There's a reason most marketing materials use professional actors, and if your strength isn't presentation, you should too. There are lots of students looking for portfolio work (at very reasonable prices).
