Sounds like an exciting move, congratulations on that and your willingness to get rid of excess clutter in your life!
After selling the higher-end stuff on Craigslist, what I would do if I really wanted to get rid of most everything, is to hold an auction right inside the house or garage. That way everything will be guaranteed to sell at some price, or you can just give away anything that doesn't. Bin loose things together rather than selling everything individually so it won't take forever. For example, you could auction off all your pots/pans together, or all the plates/dishes, etc. It doesn't matter if something only sells for one dollar, take it and move on! And people will bid up the nicer stuff.
By guaranteeing a sale of everything at some price, you'll probably end up with a pretty decent chunk of cash at the end. This is generally how estates dispose of entire household contents.
