this will be my first hardscape job and i figure i would ask you guys for some advice on the pricing. AS you can see in the pictures there are already rocks in the ditches. The job is to remove all of the rocks from the ditches except for the ditch running along side of my truck. Then pull apart the poorly made retaining walls pictured(old man from her neighborhood did it) and use the bricks to build a retaining wall on each of each ditch around the culverts. Basically put bricks where the rocks are now. 5 ditches total I have some ideas on the time it will take and it should be all labor no materials needed. so what are yalls opinion on the time and price for this job?
