You should be able to sell Jarvis to PR, marketing, and communications companies -- at a price point much higher that you're currently selling on your homepage.
Have you conducted any cold emails/sales call campaigns to those clients? I'm pretty sure you could find buyers at $100/month, if not more. I see the immediate value.
How have you been marketing this so far? What audience have you been targeting? What routes have you been using, i.e., PPC, direct outreach, cold calls?
I would be interested to work on this with you: j@greenaway.me
