What is the best way to sell my stuff fast?

I have a ton of stuff I need to get rid of within the next two weeks. These include electonics (PSP, iPhone 4, Motorola Droid 2 R2-D2, etc all include accessories and in VERY good condition), clothes (all in very good condition, only worn a few times), pet stuff (hamster cages, hamster accessories, etc only used for like a month), and a bunch of other stuff. What's the BEST way to get the most money for my stuff quickly other than a yard sale (don't have time to plan/advertise) or eBay?
