First of all: Huge respect for getting something out the door, looks really useful.

You could consider an "enterprise" tier with a special subset of features and guaranteed support. But my experience tells me this will be really hard to substantially monetize, as the customer profile for that solution is probably not spending on software until they really need to (the saying goes: selling to developers is impossible, you need to sell to their boss). Maybe a donation model or a creator-centric thing could work out!
