Try to sell this to Nike, drug-resistance organizations, anyone using "you do" as a motto, pretty much any American organization trying to push an agenda. Mass email. The price? The price they are willing to pay. It is a great marketing campaign.. you just have to convince the corporate weasels that you.do will "set them apart", and that "the competition is submitting offers". Why do I single out American corporations? I am American and I see the crap that is advertised everyday as the next biggest thing. Your domain is not crap, though, it is gold.
This domain is speculative. It is worth what you advertise it is worth, IMHO. You may not sell it tomorrow, but you WILL sell it, if you try.
GL!!
