Hi Aaron,
Your campaign is doable, you can reach your goal, but the thing to remember is that the 30 window of your campaign is not really your campaign, it is merely the money collection part of the campaign. It is the drive, the last push.
A Kickstarter campaign is a 1 year endeavor where you go have to put your idea together and then pitch it constantly, online and on the pavement. You need to build a following ahead of time and tell people "I'm doing a Kickstarter campaign in September". Your goal is to get 100 backers, which is all you'll really need, but you have to get the backers first before you launch your campaign. You will not get the backers during the campaign, you have to promote yourself and sell people on the idea before launch.
I checked out your campaign. You should cut your video time in half or more. A 1:30 video would be better, that starts off with you looking at the camera saying "Hi, I'm Aaron". You need to make a personal connection in the first 3 seconds. Then just talk with some images popping up, it doesn't have to be fancy, you can film it with your iphone.
Be optimistic, you can still reach your goal. You can still promote it all over the internet and hit $4,000. Good luck!
I'm in the same boat with my project:
