Your best bet is to work with a Realtor. I would recommend that you contact more than one, and have them give you a Listing Presentation. The Realtors will then pull information about your specific area and present it to you, and they should tell you specifically what they will do to market your home for sale. Look for a Realtor that you feel comfortable working with that has the skills (and a plan) to help you sell your home fastest for the highest price.
If you decide to use a Realtor, you will enter into a contract with them to help you market your home. Keep in mind that most Realtor's don't get paid unless they sell your home, but there are other options. Most contracts are for several months (giving the agent time to market the home, negotiate the sale, and get the transaction closed).
Before you put the home up for sale, you should make sure to have it ready. Any minor repairs that need to be done should be completed. Possible touch up paint, steam cleaned carpets, de-cluttered, thorough home cleaning, are just some things to consider. A Realtor can advise you if there are any changes that could be made to help market your home for a quick sale.
