find where the deer are using most. ask the farmer if he has any big hay bails. stack them up near where the most used trails are and make a 15ft high hay blind. you need enough to give you a sturdy base and kinda build it up like a pyramid. you need to get it in there asap so the deer have time to get used to it. if thats to much hastle use a ground blind or a tripod but you need to get them in there soon so the deer get used to it unless there is good cover around where you want to put it. good luck.
