Helping with farmwork is probably the way to go
Exactly..........any farmer with the chores they have everyday will be more than happy to have someone help. Does he have crops? If so here is a sales technique you can use..........ask him how many deer he thinks is on his propery( if he dont know give him a big number) then give him a statistic like.........each deer will eat 10lbs of food per day, multiply that by the number of deer,(you need to get some facts before u do this like how much of corn or soy beans cost by the pound) then add that number and tell him he is losing that much money per year from the deer! Here is the close....................Mr.Farmer, how does that make you feel that these deer are basically eating money out of your wallet?

See what he says then...........hope this give u an idea.
