Priority #1 is should be to get that whole lot better organized and tagged.
Treat it as a business...you woukdn't see a Ford parts department looking like that.
I used to run a Mustang restoration shop for many years and the used parts were organized the same way as the new parts, by part group numbers.
Brakes...suspension...fuel...engine...interior...body...trim...etc etc.
Looks like you might have some premium and desireable stuff there!
You need to slow down when videotaping, its way too fast to see what you are trying to describe. Remember, you know what all of it is but your audience needs a bit of time to catch up with you.
Good luck in your sales! I think you'll move the most stuff by going to some of the major swap meets. Around the midwest I' be thinking Jefferson, columbus, indianapolis, Iola.
