Naturally it depends on the two characters ... if it stands for something real, or well known, and/or for suitable potential End user's who could be very interested, IMHO. Generally, I'd say $750 (min.) - $1,250/$1,500+/+ in my view, perhaps much more with the right combination.
Would it be for a re-sale, or development potential?
Best of Luck, Armstrong.
