You can be both farmer and middleman.
And i would encourage you to do just that.
Middlemen can make alot of money.
But being a middleman is not easy you know ......
contrary to popular opinion, middlemen also make losses at times, huge losses!!
you want to be middleman between farmer and wholesale market, or between wholesale market and large consumers, like fast-foods?
do you have ready market already?
Have you studied the market well enough for long enough?
