I think a respectable person from the site that is near by could come and help you two out . Maybe offer a fee for the advice and help . It seems you have some very desirable pieces and you don’t want to get taken advantage of . I agree the easiest is a bulk sale but if you have the time .. I think you have some good money sitting there . I would love to buy it all just to go through and open it all . Good luck with the sale and congrats on the new home .
