He asked "If I was able to obtain lawn equipment from others like weedeaters, a truck, blowers, a ztr and a walkbehind, how much money would you figure I would need to start up? Can it be done with very little money?
This certainly depends on one's own definition of "very little money" and many other variables.
I would suggest starting with the basics with as good of equipment as you can afford, then evaluating where you are, if you wish to continue, and what approach you want to take. All of these and other factors determine ultimately what equipment to buy.
