Yes Hook, I like your improvement on my idea. Part of the quest could be to \"master\" the animal i.e. gain its trust and respect. The trainer could be paid a deposit (non-refundable) in order to try to gain mastery of the animal and, if she succeeds in this, pay the rest of the amount once the animal decides to join the player. The payment could be as gold, potions, ingredients or other items including new untrained animals.
Maybe a player can also come with an animal he already has and pay to have it trained in a specific skill(s).
Please tell me which other forum you are referring to then I\'ll move myself over there.
