The best thing to do in your case is to find a local auction house to sell the items for you. They would come to you and remove it all, sell it and you would get a check 14 to 45 days later minus their 15 to 25% commission. To find a local auctioneer, you can go to liveauctioneers.com and search their directory by region to find an auctioneer near you that deals in tools and equipment.
I live in Maine and I know there are quite a few good auctioneers in our state that could help you.
