I guess I've done some of these services without realizing it. Like an opening a path to a wood pile on other side of the yard, walking trail around a pond lot, an area for dogs. On the farms, paths to other barns and open a path to top of mnt (various reasons). With the latter, it wasn't pretty, but it worked.
Having worked for a high-end landscape firm in yrs past. I can respect what their level of service. One needs to know how to handle clients questions and be ready to explain what this service does AND doesn't do to turf, stamped concrete, marble, granite curbing, etc...
It would also held on the employee side if the shovelers weren't treated as "having lost in life". Of course, how many employers would be willing to pay double or triple time for those shoveling driveways? Yah! Try it, see how many would show up early at 2am ready to go... and the next time. Be real easy to keep help during busy times... imho
