In my opinion, The reason that you are seeing such a large difference in opinions for times and prices is because some people maybe factoring in that these bushes don’t appear as if they where trimmed recently. They do not have a clear and definable shape. I can kinda see what they should look like, but that’s different than a very defined cut location. This means your taking off a lot in the form of trimming but your also having to step back and define what the bush needs to look like, and then make adjustments. The second problem with 5 foot tall- you might need a ladder and that will significantly slow things down. If the top of a bush takes 30 mins to trim, it will take 75 if a ladder is needed. Even if it’s a small ladder. You have to move the ladder, walk up it, stand, balance, use your trimmer, then walk down, and move the ladder 4 feet, starting that cycle again. If the bush was very clearly defined, I would do that job without a ladder. But because it needs shaping, your going to want a good view from the topside to ensure that your straight. I also can’t tell what the land behind the hedge row is doing, if it’s elevated 18” compared to the front side , then no ladder would be needed at all. The other problem is the top will take longer than the sides. Clean up can’t really begin until the entire bush is done. So one guy does the sides while the other does the top…. But the guy on the sides will finish first and need to wait for the top guy to finish, unless you have 2 pole style trimmers.
So assuming 8-12” trim, no defined shape, possible ladder needed.
Trimming both sides and the top.
90 mins x 1 guy to trim per side. X 2 sides.
30 mins per side x 2 sides to clean up
3 hours to trim the top
30 mins to clean the top.
30 mins of break time.
8 labor hours total.
I would probably bid 9-12 labor hours.
