I would think there should be plenty of people wanting winter grazing for sheep, how many acres of cover crop do you expect to have in total?
The "Farmers Guardian" would be your best bet!
Need to finalise things but between 6-800ac quite a big block will go winter beans this time to ease us into this and spread workload / cash flow
I keep getting told there should be loads a people keen for the winter keep but quite how I find that man I'm not sure
Maybe I should try an advert in my own forum !!
