One option is to use romex wire and fasten boxes to the floor joists. Drill holes at approx center of the joist and fish the cable through them back to the panelbox. The other option is to use EMT ot PVC conduit. EMT is metal tubing and needs to have gentle offsets to enter and exit the boxes along with EMT screw or compression fittings. PVC is the same only plastic. It uses socket weld (solvent cement) fittings and adapters. outlet boxes for this type can be metal or plastic 4" square pvc with raised duplex covers. the metal boxes can be 4" X 1 1/2" deep junction boxes with 1/2" raised covers. The metal EMT doesn't need and equipment ground but it is still wise to run a green ground along with the circuit conductors. PVC requires the green ground to all boxes and outlet locations.
