Try watching HGTV shows that talk about how to get your home sold. They have great suggestions for any situation and you don't have to pay someone to do it. Things like, open all the windows & turn on all lights and lamps because light makes a room look bigger, or tilt the sofa at an angle for a bigger look. Maybe put some of your larger pieces of furniture in storage until the home is sold - big things like entertainment centers can make a room look smaller. You can also rent furniture from places like Cort Furniture Rental to help fill in any gaps or replace larger pieces temporarily.
