Lots of late 70's Fender Strats and later model Fenders and Gibsons. Not what I would call vintage or necessarily collectible, but it's certainly a "collection". If you buy 30 pieces, they average $2k each, which is probably national retail value, so why buy 30?
Take them to a Guitar Show, there are several across the country, you will have better luck there. Perhaps be flexible and sell one or whatever the buyer chooses, instead of constraining them to a $60k package, this deal will be a long shot
