Small concrete cutting job

Hi, I need three holes approx one square foot cut in a concrete path where I need to install new supports for a small wooden garden retaining wall. The previous supports, half rounds, rotted out & I dismantled the old retaining wall but the concrete is hard to break up manually. Would be good to cut 18 inches deep maybe into the soft/broken rock underneath the path if poss for the new supports, though I could do that with a digging bar if a hassle. Also keen to get an old dug-up pile broken up into a couple of pieces so I can dispose of it more easily; I buried a chisel in it failing to do it myself. Towards end of this week would be neat. Photo of the path and the separate pile should be attached.
