I have to ask why are you trying to sell you home yourself? Are you aware that it is proven that a house will sell quicker and usually for more money when a Realtor is involved. What do you know about the requirements of your state to sell a house? Where did you get the comps to price the house, what if you are under priced, you could be losing money. Are you willing to let just anyone who walks up or calls into your home? Without consideration of the money you stand to make or lose in this sale, first take into consideration your safety and that of others in the home.
If you have to ask here how to market your home what other questions have you not thought of to ask?
Hiring a professional should be the first thing you do, let them spend the money to market the house and if it doesn't sell you haven't spent a dime.
