HIGGINS,
dont get me wrong, but it is not all beer and skittles, you say it is just a case of finding the big farmers who are willing to pay, that is not the difficult part, if you advertise effectivly and build a good rep over many years the work will come, No the difficult part is providing the service to the customers expectations everytime, finding the money to set up in the first place, insurance, advertising, tidy vehicle that will give confidence to the customer, remembering to keep back a large chunk of what you earn to give to the tax man, accountants fees, etc etc.
