No, no, I meant the 3 hours per month on her laptop, and the 57 hours per week she's working, but not on her laptop. Maybe she's a ho (a busy one at that!) that does her own bookkeeping and accounting!
Hm, is there a market there? Tracking of tricks, scheduling hoes, budgeting, tracking money in drug/alcohol funds, and oversight dashboards for pimps? I mean, they need software too, right?
Can't do it as iOS app (would never get through AppStore, and I bet most pimps can't jailbreak their phones), so it's either Android or HTML5, but it might get a decent market.
The real problem is that the target demographic is hard to monetize. Can't sign 'em up with a trackable CC, they're not a good target for advertisers, and your service is likely to attract a made-in-NSA parallel construction from FBI and friends.
