You will need to contact a Realtor, list your property with them, then they will upload your listing information.
A Realtor survey found that the buyer that first sees the home they purchase sees it with a Realtor, so in order to get maximum exposure you will need to find a Realtor that has broad marketing capabilities.
Another Realtor survey of owners selling their properties without professional representation found that on average the sales price is about 16% LOWER than those listings sold by Realtors. So to get top price for your home, listing with a Realtor is the best way to go.
The same survey found that 85% of owners eventually list with a Realtor, 5% sell to someone they know, and 5% sell to someone they do not know.
If you would like I would be honored to provide you with a Realtor to interview that is a market leader in your area, at no obligation. I suggest interview a couple of Realtors, compare, run the numbers, then you decide how to proceed.
