For me, a dollar per minute is tough even with 4 years experience and all the tricks and equipment and stuff... Price things at a dollar/minute when new, and I think you'll find yourself somewhat short of work... I could be wrong, but it used to take me twice as long 4 years ago, so half the secret of $60/hour is being able to do twice the work in the same hour that used to cost $30...
Then there's fair pricing. You want to price the yard for what it's worth, like around here an acre goes for 55 dollars, that's the price for an acre lot whether it takes 10 minutes or 2 weeks, it's still 55 dollars.
Now that's in Virginia and realize things in NY are a bit higher, so maybe acre lots in NY go for 60-75? The price drops in a strange way, 1/2 acre is NOT 1/2 the price of 1 acre.
Let me see: (VA prices)
1/4 acre $30
1/3 acre $30-35
1/2 acre $35
2/3 acre $40
3/4 acre $45
One acre $55
So, add 15 percent for NY? If it's more you can adjust later, here's my guide:
1/4 acre 35
1/3 acre 40
1/2 acre 45
2/3 acre 50
3/4 acre 55
One acre 60?
Keep in mind over time as you gain experience, you'll likely want to price flat square lots a bit lower than the hillclimber extravaganza in the woods, but I think if you use the above prices as a guide, that should help get you started.
