Don't know your area at all, but generally speaking you want to price your home slightly lower than your competition. Look at the most recently sold comparables and your present competition that is on the market now and price your home better than theirs.
Besides that, do the obvious: declutter, neutralize colors, clean (both interior and exterior).
If you have an agent, make sure your house is marketed not only on the MLS but also all major real estate websites(such as this one). Pictures are second to price in my opinion- very important.
If you don't have an agent you should consider hiring one for a flat fee just to get on the MLS, although I'm not sure how this works in your state.
With all that being said, it almost always comes down to price, especially for a quick sale.
