Friend or no friend, you have to do whats right for you. It sounds like you should have listed it on your own. You also have a specialty property it seems. There are other sites to market on that specializes in your type of property. 3 things to consider when you want your home sold fast, it must be priced to sell, have very good photos (hire a pro) and marketed. Some Realtors know how to market and some just stick your listing on the MLS and hope for the best. Before listing with an agent you should find out what methods of marketing they will do for you.
Jeff, I would consider using Facebook, You can create a page very easily.
