need help selling wow account

[yung meme god]

hey! i dont know where else to honestly post this, i was wanting to sell my gladiator character but im unsure of how people do it

i heart most people just xfer the toon to a new account, then sell it like that

if i do does it lose all its pets and just keep the mounts bound to achievements?

hoping someone who has done this before can help me out, i dont mind paying for your time\help

thanks!
