I just finished this job there is still a bit of work left, as the pave company needs to finish their end. I used approx.. 350 wallston blocks. 4 h x 12 w x 8 d and used about 45 sq feet of 4 x 8 standard pavers I do believe i under charged the job! i think i shouldve charged more. oh well done now! quick guesses of what you would charge. only thing i had to dig out was the satirs the wall areas were already excavated by the paving company. let me know what you think!
