Depending on the quantity you're getting, filling big garbage cans with manure and loading your trailer using a hand truck might be easiest.

That would also make things a lot easier to bring into my yard.. and hell, I could just apply my BSF (extremophile composter bugs) direct to the cans.. It would be a bit costlier sure for the cans, but it would be very efficient with time and money in the long run I think. Thank you for the suggestion Dash! That's like my 75% desired plan now 
Just have to see how much it'll all cost in cans and transport.
