It does limit potential buyers if the only way to find out what is included is to pop down to Dorset in the next 10 9 days. Also, it is a lot of money to put together quickly together with transport and storage etc.
I would possibly be interested but it is a bit of a punt without a full list and when there may be only a couple of hundred really good records in that 10,000 - you could be left with a few thousand unsaleable records. My missis would kill me too.
My advice would be to split them into blocks of 20 or 50, all listed, and then put them on ebay over a few months. More chance of selling, probably more money made and each lot would be postable. Sprinkle the best records in with the lesser ones to give more chance of a sale.
Best of luck with the sale though Vince, it would be a nice result if you sell them like that.
Cheers
