I assume you're on Bronzebeard US which is a PvE realm.
Just make a horde toon and level up to 11 and then get the quest. If I remember correctly, you may need to level a few more levels above 11 in order to complete the prerequisite quests. When I did it several months ago, I think I leveld a rogue to 13 or 14.
Plant your Alliance Hunter at the spawn point. Logout.
Log onto your Horde toon, blow the horn, summon, and logout.
Log back onto Alliance Hunter and tame.
Win.
It only takes maybe a little over an hour to get your toon to level 11. Probably quicker than it would take to find someone to help you on Horde side.
