The work is just cleaning out river rock and weeds. Removing rock, washing, pulling weeds and putting it back. Not the entire yard, just sections. No mowing, blowing or weedeating. Just the labor of removing rocks.
I do the rock around our house in sections at a time. I listen to the radio and it goes by pretty fast, but it is work. I pull, dig rock out, smooth and replace. The first year we lived here, I paid 1,400 for the rocks getting cleaned out, mulch, weeds pulled, trees and scrubs trimmed. It killed me to pay it, but there was an entire crew here busting their butts from sun up to sun down. It looked fantastic, but in four months it needed to be done all over again! Lol
Once clear, don't forget to put down some Preen 3 times a year. You won't have weeds in your rocks again. Or rather, not many. I agree with Sheddy. Working and cleaning rock is a peaceful job to me with great rewards in a little time.
