Here are three quick things I see:

1. Always have price on the top menu bar. don't make me scroll to the bottom of the page to see what it costs

2. Need on Chrome at least some padding between the headline and the green box

3. Why are all the videos cockeyed? Its possible it is a styling thing but you are better off having them level

I love the idea, just not certain that people giving testimonials will submit video ones. If they do a video testimonial could be a much stronger one because you could see emotion in a video which would make it far more powerful.

Thank you so much for going through my product and actually reviewing it, it means a world to me. I'd definitely make the changes you've mentioned.
