If you can get neighbors to do a concrete project at the same time with the same contractor, you should get a better price. Concrete companies charge a "short load charge" for less than 5 yards of concrete. Extend a golf cart driveway is appox 2.75 yards. A full concrete truck is 9 yards. "Short load charge" is about $120. A yard of 3,000 PSI is about $100/yard. Fuel surcharge is $15-40 per load.
