RE: Hunting Proposal..please read
I like it.
But here is my advice. Try to get an answer face to face. If you get a no,ask them to please reconsider and work in your letter for them to have. It's always harder for someone to say no to anothers face then it is over the phone or such.
I would also work in other things that you could do for them besides giving them meat (they may not want it, a lot of people don't). Things like painting, welding, etc.
