I think you could arguably charge based on frequency. Weekly job -> free. Daily job -> 10c a month, Hourly 50c a month, more than that, pick a price. Definitely useful but then you're also going to need a way to make it a distributed service because people aren't going to want to have it not work because your single Amazon instance has tanked. The number of businesses who have problems because timed jobs don't kick off is insane and this might do the trick but you need to avoid moving that pain point from their own systems to you.
