your hands are numb arnt they ?
have you ever cut the concrete, then popped out 2'x2' squares, hand truck out the door?
company i worked for had their own concrete cutting/coreing crew
we did a lot of renovations, where we had to cut a trench thru the building.
those guys were pretty slick. cut both sides of the trench, then cut cross ways,
instead of busting concrete, pop up the sections with a prybar, tote em out
