It all depends on you wether you will hire people or not and also the locality where you want to farm and the type of crop you want to plant too matters. Start a small scale farming first to see the up and downs.This would be expensive. At the end of those farming activities you will come to realise that you will not be able to make up the amount you use for everything.
At least it is not everything that I should be hiring people, but I have to.
