Based on your figured of a tree every 20ish feet I figured that works to about a spot 400 ft having a tree. (20x20). On 4 acres that works to around 1000 trees. If you spent 15 mins per tree that's about 270 hrs of labor.

20×20,..the 400ft...but you lost me on the = part. Think you were out 600 trees there Vf
its pretty important to know your spacing
Example:
An acre is 209ft ×209ft..going on memory.
so thats 10.5 trees every 210ft
10x 10 = 100 trees
.5× 10 = 5 trees
105 trees per acre at an average of 20ft
But at 30 ft spacing your at 30 × 7 = 210 ft
7×7 = 49 only....big difference!
Thats either 420 vs 196 trees..
Got to sharpen you pencil.
If your have a logging tape or hip chain & compass, do some random plots measere out 104ft
North, South,East,West. Do a couple of 3 random plots through an acre then x by 4 as thats a 1/4 acre. 52ft sq is only a 16th of an acre. May work better with the big plot me thinks. It won't lie to you.
Things to think about?You have retention falling on one side it sounds it is a narrow long strip? Things that slow it down.
How about the road? Are you required to have certified trafic control personal?
Or at least responsible to bring in a spotter for that time? Bottom line. You need to know if your dealing with '50 or 105 trees'
Per acre. The rest I would break it down per tree. Since its just you then only you know. If a job was big then it would be based on what an AVERAGE guy can do.
