You are assuming we are charging per hour.

Yes I was. But I wouldn't mind being proven wrong. My guess is a form of online subscription, since you're probably looking for committed players, ie steady cash flow. The monthly fee is too low and just as unsteady as an hourly rate. You could probably get by with fewer players if those players were willing to pay for the long haul. So my guess is subscription rates of anywhere from 1 month (highest monthly rate) to 1 year (lowest monthly rate, but multiplied by 12). Maybe even lifetime, for some amount in the thousands.
