Hello,
It looks like you have a great product, as well as a nice team to back it up. The slow start you've encountered may be due to the high price, but as you wisely explain, that's the true price of the product you hope to produce.
So at $1,300/$1,500 for a base-level pledge, you need to engender confidence in someone who is browsing your page. I can think of two things that might help:
1. The 'As Seen On' graphics don't appear to be clickable. Can you enable some links to let potential backers see what these news sites think of your product? These outside voices will assure potential backers that this is a solid product worth their investment.
2. This may seem minor, but I noticed some issues with grammar, spacing, etc. This shouldn't have any bearing on your technical skills, but these things may turn off a casual browser. You might find someone to do freelance proofreading through your local library or newspaper.
Best of luck!
