What Pacer said, it would be great if you could compose a list of what you want, preferably with the pets' names, levels and what possible mounts you'd want in exchange for your. That way we can all go on and try and match that list as close as we can. It would also give all of the ones interested in your pet, a fair chance at trying to meet the "wish-list".
If I were you Id post the current "best deal" that you decided to go with so people could counter offer. Additionally it doesnt seem like you know a lot about pets so you could be doing a horrible deal. Thats just my opinion anyways.
