For "surprise me," why wouldn't you open with: you can get (one example of x) for $500 or (one example of y) for a million bucks. Do you have a sense of where in that range you are looking? Educate the buyer on what the range is and how wide it can be.

Otherwise it looks like pricing for what is in their wallet, not what you think the thing is worth. Especially with domaining where prices can vary wildly on kind of the same value of domain.
