First scam idea, so cut me some slack..
So the idea is to look for 40-60(level) noobs, who you suspect don't have there mount yet. hint's : There a Warrior wearing cloth armor etc etc.. Anyway you wisper them with a messege like "Hey I could summon you a mount for 20-30g(your choice)" and if they are noob enough they will ask some questions like "Is it perrmz0rz??" of course you say yes.. and happily take their gold, and be like, "it takes 24 hours to take effect" then just ignore them.. Gl..
Please give feed back.. First scam, so go easy..
