Looks great, not sure about the pricing. Maybe offer a 50 or 100 dollar package, and charge the full 499 for the ultra fine tuning secret sauce package? I'd understand if you don't want to dilute your content though. Maybe offer as a monthly/yearly subscription? This seems like a topic where regular updates and podcast style discussion could be valuable. Perhaps not to the extent of creating a community, but certainly to the extent of creating a regular audience.

The hard/expensive part is not writing a patent. You pay a knowledgeable lawyer to shepherd it through examination and defend it down the road.

Good luck getting a software patent.
