Here's some real advice from someone other than a jaded express box monkey....
That pay structure can leave you high and dry if the volume isn't there. He can decide to add another truck and take some of your volume. Make sure you are given a minimum guaranteed stop amount or a minimum DAILY pay.
And 110 stops with 40 miles can be easily done in an 8 hour day with an HD route. If you really push it you can probably knock it out in 6 hours.
110 looks to be the minimum. I asked him if that was ok and he said for now yeah, but when holiday time comes it will pick up.
More I think about it, more I think I might go the seasonal route. If it's as bad as you guys say, then I'll leave at the beginning of the new year, so I don't end up being long term with them. And if for some reason I like it, then I stay on. Extra money will be nice, and I can use the time to figure out what I want to go back to school for in the spring semester.
