I'd turn them into popsicles and ice cream before they went bad. Then I'd get an ice cream truck and do a vehicle wrap on it, branding it the 'The Avocado Ice Cream Truck'. I think it would do well here. I live 2 miles from La Habra Heights, the birthplace of the Hass avocado.
By the way... avocados run from $1 to $2 apiece in my area... and when they're just $1, it's usually because they're quite ripe and about to go bad. So you're asking me to dispose of from 5000 to 10000 avocados.
I love science fiction, so how about... I put them in my time-stasis chamber, which preserves food by slowing time down to a crawl, except when I open the door. Then I sell them or give them away as people want them, and/or eat them myself in a demonstration of my soon-to-be-publicized "Avocado A Day" diet.
Or maybe I'd trade half of them for $5000 worth of sweet cherries or persimmons.
