If all you had was a shovel, you could make $1000 with about 35 man-hours. Add a machine and you'll spend less time getting to that mark. Of course now you have to pay for the tractor and the implements, gas, oil etc. See where I am going with this?
It just depends on how much time you want to spend and how much you want to invest in terms of equipment.
BUT...it can be done!
If you can afford to feed it, you can afford to pay me to cut it.
