My 2 cubm comes on friday and cost £300. If you are short you will need to get some more , so over order a little. Pumps can cost £300-500 and need to be booked in advance. 2 cubic m = about 50 barrows. So you will need 2 people if you don't have a pump.
Up here the cheapest suppliers have mix on site wagons- tell them roughly how much you want, pay the extra £25/cube for barrowing and get exactly how much you need and no looking for a big hole to lose the waste in
