If you were going to do it at all, which I wouldn't, I would do it with a rifle that is already beat up and you aren't very attached to. You would definitely need to work out some form of collateral and also what to do it is gets messed up, which I would guess would happen a lot more then you think. Keep in mind that people will take care of a rifle that was loaned to them by a friend but I doubt most people would be very careful with something they pay for to rent. It would need to be some sort of you break you buy policy. I think a daily rate with a minimum amount would be the way to go.

But I wouldn't if I were you. Way too much of a headache. Plus if it is 2 grand you might as well buy a DR and then sell it after the hunt IMO.
