30
You simply said it was a 300 mile trip. From where to where is important. If it's not a strong backhaul area, then your 300 mile trip becomes a 600 mile trip because your carrier is going to do it as a rounder. We're down to $4.00 a mile now.
You didn't mention anything about the time it would take to do the load. Is it like 6 hours to load it and 6 hours to unload it? That's important as well. Overall, maybe your carrier is going to wrap 24 hours into getting this job done for you. At a hundred bucks an hour that's pretty reasonable. I'd charge you $165.00 an hour.
Get that per mile crap out of your head ... TIME ... everything is now about TIME.
Assuming all things are equal, where it's a quick on/quick off load going from Toronto to Pittsburgh where it's fairly easy to get a return load, gouging is one word to use to describe that rate, but here's a better description ...
That is what's called a F*CK-OFF rate. Every shipper, receiver, 3PL, broker, and carrier world-wide, if they are doing their job correctly, has a special page in his or her ledger for people who supply F*UCK-OFF rates. Get my drift ???
