I think you are right about not advertising it directly using such services. I always think a site can be devalued simply by being put up for sale in a public way.
Directly selling it may well be the best way. You may well have people who are already interested. People within the industry who know you are getting to that stage. It might be worth putting some feelers out to gauge opinion.
