I know what you're going for, I know the phrase. However, I don't believe its so strong. The correct spelling would be "whoopty doo", "whoopy-do", "whoop-de-do(o)"...something along those lines, from what I've researched on the net. Even then, not thrilled
Came across these guys: Home | Whipty-Do ...drop them an email, offers accepted (see if they care to own it). Hope you get a bid
There is a potential lead Whipty-do.com. Reach out to them with a make offer/$799 kind of pricing. Try and close the sale on whatever they offer as their last price.
