I got a new customer that I'm working with, on new landscape install and design. They want a perfect looking yard and don't seem to have an issue with cash or prices. Apparently, they just had some new St. Augustine (Floratam) sod installed but the installer did a hack job on the grading prior. There are lots of peaks and valleys, which make it difficult to acheive a smooth and manicured look no matter which pattern it's cut. How well do you think the end result would be if I were to take a sod cutter set a little deeper to pull the sod up to regrade and then lay it back down? How much do you think you would charge for this per each 400sq/ft area? Some dirt would need to be brought in also. Likely less than 4 yards which can be done at the landscape install. Unfortunately, the job was so bad that filling in the low areas won't do it. Any advice?
