Just a suggestion on pricing: drop the lifetime option. I've had a bunch of perpetual licenses I've acquired over a lifetime, and nearly every one of them have said "we have no record of you" after 5+ years. I know, I know...save the receipts and all that. But it's just frustrating. Don't put yourself and your customer in a potentially problematic position of he-said-she-said. When you have recurring revenue with a more mature product (and a way to track those subscriptions that you won't end up scrapping), re-consider the perpetual license.
