My backyard is pretty average. Around 6,000 square feet I think?
Depends on where you live and what kind of work needs to be done.
I live in the midwest and paid $1,900/day for a crew, but this was a few years ago. My brother paid something around $2,400 per day last year.
We also didn't do anything crazy, mostly ripping out some ugly trees and bushes, and replacing it with sod.
Damn that's pretty high. I guess it is a lot of labor.
This seems to align pretty well with what I saw on here https://www.angi.com/articles/how-much-does-landscaping-cost.htm
I worked on a landscaping crew one summer. About $2k/day. Depends on the work required as well.
