70 Boost?

Can I get a 70 boost for half the price. Don't care about the profession bonus I just wanna skip the content I find annoying.

I wouldn't mind playing through WotLK, Cata, MoP and WoD again. I haven't levelled a character past ~60 in a long time. I don't think the story as fun or interesting excluding a few zones (the starting quests for the undead even leading to Tarren Mill were entertaining).

Would anyone else want a jump to a specific expansion?
