Hello,
For me, we deliver a lot of our hay sales but I'm more of a hot shot trucker. Meaning truck and gooseneck trailer. Not semi loads. I can haul 14 4x5's at a time. For my hay, I charge $5/bale for up to a 20 mile radius. Then $2/loaded mile beyond that. So for 14 bales, 50 miles, it would be $130 for the delivery. So that calculates out to $9.29/bale. But some people don't have the equipment so they are o.k. with it.
For your case Rhett, if a semi can haul 22 bales at once, I would figure $3-5 per loaded mile. But this is for Missouri so not sure about Texas. So using $4, a 50 mile delivery would be $200. Calculates to $9.09/bale. Truckers like longer distances. You might find it hard to find someone willing to haul 10 or 20 miles for $4 a mile. In that case, it would probably just be a fixed fee per bale. And then throw diesel prices in there. Last year we held our deliver prices flat even with gas/diesel higher. Our customers really appreciated that as we did have to raise our hay prices considerable due to fertilizer/fuel.
If it helps, I have my hay fee schedule on my website highfillfarms.com. Under product and services. It shows cost for different delivery scenarios.
