I don't want to link-bait, but I did write a blog post about the best crowdfunding practices.
I think there is a few good steps.

- Find your best competitor. (how did they succeed)
- Where does your market exist online. (reddit, facebook, instagram, specific blogs, etc)
- Create a trailer & landing page and try getting press aimed at your specific audience.
- Launch the Kickstarter with hype & have a marketing plan + press ready. With those you could easily hit $20k.

Here's the blog link if it will be helpful.
