Question….?
Here is another idea. See if you can find a somebody who would be willing to help you with the task of sorting, photographing, listing and shipping the items. A big job like that should probably see some cash change hands. Maybe you could agree on a percent of the sale price. Plus, if you really want to get rid of the stuff quickly, price it accordingly. I am not saying give it away, but price it according to how quickly you want it to sell.
OR you could lay all the parts out, take a video that would include everything, post the video on YouTube and then post that in the parts for sale. Then you would technically have pictures, and you could just make up one really long list of items and prices.
