Before and after pictures of a concrete patio I built.  Working involved:

-Tilling the land
-Remove excess dirt
-Tapping the ground to create a smooth, hard surface
-Placing/smoothing leveling sand
-Placing each of 50 pound bricks
-Brushing in filler sand to fill spaces between bricks

This project took about 4 days.

I also have a chainsaw and hedge trimmer to help with trimming and small tree removal and am also happy to provide mowing assistance.
