We just did this... I did NOT want to hire a dumpster (both because I hate to waste & because they are crazy expensive) but that's probably the easiest & fastest option. What we did though was list everything on freecycle for a week or so, then dragged whatever was left out to the curb. Almost everything was gone by the end of the weekend & the last few things (minus 1 or 2 that we are sneaking into regular trash) went by about 2 weeks later. Didn't like having all the junk in front of my house but it was great to get rid of stuff in a more sustainable way.

Oh and I also made a pile of the smaller, better condition items and dropped them off at Salvation Army.
