KENT it is! I've been wanting to try it for a while, and here it is definitely the better buy.

(Can we mix brands in the larger order, if some want IO?)
How much simpler will this be (i.e., how does he want it handled?) Can we pay individually, or does he need a lump sum? I imagine some sort of commitment would be needed...
I'm good with this sort of deal - I know what kind of work it is for the arrangers (as Tony mentioned about the bags of sand bulk order), and this deal is fair enough.
Others?
