I think you will find pricing can vary area to area. Just call a few pumpers and ask. Your concrete supplier may provide pumping services as well, and if not they will have a list of pumpers they like to work with.
You may have a price diff for small and large stone in the concrete mix - smaller pumper needed for smaller stone. I did a patio with smaller stone to get the price of the pumper cheaper vs. larger stone for the slab on grade foundation for my 24x30 workshop.
Other options are to rent a concrete buggy or get a concrete trailer if you can get either of those in there.
