Besides that, I think there may be some violation in Blizzard's rule book for what you are asking for.
It's ok to "give" the beta keys away, but it's not ok to "sell" them. I don't have a link for that handy, but I posted it somewhere a few days ago I think.

Oh, and now I think of it, it's my wife's birthday soon (probably) and she'd love one of those keys too (probably). *cough*.
