The app sounds interesting, and the website is polished-- but I don't think that you are going to be getting a lot of sales via the website. That's not how "Enterprisey" software, even at a low price point of $1499, is usually sold.
I think you're going to have to give some thought to your customer acquisition process (which is going to be different than the usual B2C or B2B methods you read about most often on HN.)
