Make sure you target the right people. Logistics is something the lumber yards handle, not the contractors. The contractor drives there van to the job, unloads, works all day, loads up, and drives home - that is all their logistics. The lumber yards drive to many different sites, and often do have partial loads that could be combined.

I don't think there is much scale you can pull off there though. They have been doing this job for a while and can figure it out.
