I don't care who they are or what their problems are. If you pay in advance you're usually going to get screwed. And when someone already has a couple of my deer and hasn't gotten them back to me..... I sure wouldn't take him any more. That said, I'd go have a big conversation face to face with an expected date of completion that's satisfactory or we're going to small claims court. I'd also like to see my horns at that time to make sure he's still got them. Big horns bring big bucks with decorators these days. He could have sold them. When you mix business with charity orpity or help, it usually ends up a gift.
