Any toy car collectors on the bbs ?

I've been working at a ladies house this week who's husband sadly passed away last year One of his legacies was to leave her with a massive toy car collection . Over 8.000 to be precise. Mainly lledo models all in cabinets and a vast proportion still in boxes . She doesnt know where to start in the process of selling them because she has no idea what they are worth . Ideally she wants to sell the whole lot in one go, but will listen to offers for some of the more valuable/rare ones ..Long shot I know, but does anyone on here have an interest in car collections, or know anyone who could help her ? ..
