I made a lot of money on rural routes based on core zone pay. From the literature, it looks like Amazon is offering something similar. My average core zone pay was over $100 a day. And there were relatively easy ways to manipulate the core zone pay. I got mine up from $80 a day to well over $100 a day just by understanding how it worked.
If the ISP has only rural routes, and hasn't been able to get higher compensation for them, it is his own fault. I think the Amazon system will be a lot better than fedex ISP, based on the overall satisfaction that people who are working for Amazon report overall. It looks like a pretty cheap entry price, compared to having to by an ISP ongoing business. $10,000, and no money down vehicle leases means all you need is the ability to provide drivers. And Amazon says they even offer help with that. For qualified. skilled ISPs, if there are any, it should be a natural leap.
