Sesame ?

Hi,

I am trying to make two of my friends discover the beauty of WoW pre-MOP. We're currently on TWoW and spent the entire month leveling up to 60. Now, I am dying to make him see what happens behind the dark portal and then, explore Northrend.

I was wondering - is there any sesame system available? To at least level 58 or 60 - just so we can get our adventure where we ended it, without redoing through the whole initial phase and straight into the extensions. I am more than happy to donate per character. I did see that there is a possibility to trade character for credits but that way kinda destroy the ability to customize it.

Regard
