This has got to be the biggest joke I've ever herad. babysitting six guys? holy sh!tballs talk about insane. Being a CFI in a king air, yeah right. Before long at least one to two of the owners will stop paying. All six will fight over time in the airplane. Sounds like none will respect giving you time off. Good luck finding time to get a 135 certificate let alone time to use it. They'll be bitching at you for "wheres my charter revenue, punk". I give this a year before it's sitting on a ramp with missing logbook entries, deferred maintenance, and half a dozen liens. Then Johnny bank pilot will get a ferry permit and poof!, it'll end up in FLA to start it all over again in two years.
