Legally drafted Grazing Agreement Template

Hi

I need a comprehensive, legally drafted Grazing Agreement Template in Microsoft word format which I can use to resell to my customers. It needs to be easy to follow and ideally come with explanation notes on how to complete within the document. My bid is £30.00 even though it only lets me put in £50 as a minimum. Happy to use existing one rather than having one drafted from scratch as long as I am legally allowed to sell it to my clients.

Many thanks
