I'm a small hobbyist - I've done business with other small hobbiests. I've even done breeding loans with other small hobbiest FRIENDS, and our personal relationships are very casual - however, we have 2 and 3 page long contracts that spells out EVERYTHING so that nothing is mis-understood about our agreement and expectations are clearly laid out.
