I would suggest craigslist.org as a great way to advertise.
BTW, I 'd also suggest interviewing a Realtor if you are serious about selling. Owners selling without professional representation only succeed about 10 % of the time. Most of the time they eventually list with a Realtor. So if you interview a Realtor, you'll learn some things. If you can sell on your own, great. If you decide to list, you can switch to Pan B right away and not lose itme.
