More subscription types - allow me to pay more for a increased message cap easily

I feel there is a need for more subscription types. I keep hitting the ceiling of the “40 messages/3 hours” cap.

Signing up for the Team plan is not an option for me.
Could you please come up with more subscription alternatives that are more expensive for singular individuals?

I’d gladly pay more for an increased message cap, and I’d be willing to do it annually as well (I’m guessing that makes the financial forecasts better?)
