Create a Kickstarter Pitch Video for a Groundbreaking Green Living Seniors Project

I am preparing a pitch for a Kickstarter campaign & I have a draft video that basically has the nuts & bolts of the project & the story, but would love some help to make it more professional version with a compelling message. The video would need to be 2 - 4 minutes in length. I can send you my current version in Windows Movie Maker to edit. It needs a lot of help. I'm certain you'd want to use it as the inspiration & create a whole new video. I need something inspiring & exciting to help spread this message which is a groundbreaking green living project for seniors living! It would be a fully commissioned project, if we get the funding, I would pay a large commission. But you wouldn't be paid for approximately 90 days after the submission until we knew if we got the funding support. The fee if we get the funding would be $7,000.
