Simple concept! I have a few gigs on Fiverr.com making about $300 per month... I am withdrawing my monthly income, and investing in gumball machines. Those machines inturn make monthly income. Each machine will average about $25 per month, some in the $100 range, some $10.....Goal by the end of next year is about 100 machines.... 100 machines x 5 vends a day x .25 each vend = $ 45,625.00 a year Once I expand to 200 machines, your approaching 100k a year.....Plan on expanding to toys etc, they sell for .50 - $1.00 per vend.
