Very diverse answers.
Here in Fort Worth, square bales will sell for $8-$10 in Aug-Sep, so the stuff is fairly valuable.
I am going to lime/cultivate/weed/seed/fertilize, etc. I just don't have a baler. I think I will take a look at the pay per bale idea. If not, trade some of the hay for the service 2/3 share seem very high, but I really don't know what I am talking about.
Thanks
