I have an app like that. These aren't robots though. One of my sister's lifelong best friends volunteers for one of those organizations. She literally spends 4-6 hours per day sending out texts messages and making phone calls.
I get these fucking texts all the time. One for "Joe" and one for "Lara". I like to fuck with them from time to time. Gonna text her back tomorrow morning early as fuck.
Shouldn't be too bad. @Willy Leadwell and I loaded a 700lb safe into the bed of my truck by ourselves and me and my old lady unloaded it. 900lb with 3 people shouldn't be too hard with the right equipment.
If you're in Cherokee County all I have to say is good fucking luck. Don't even get me started on those fuckers. Marvin Hemeyer would have demolished their office a long time ago.
