Advice on house clearance in the Cote D'Azur

Hi there, my French aunt recently passed away and we have inherited her property. We will have to sell it sadly, so need to clear the house. Does anyone have experience of how to do it? She was a real hoarder and there is a lot to clear. Items of worth we will either ship back to the UK or use a local auctioneer, however how do we dispose of general household stuff (such as the contents of her garage, crockery, linen, a mountain of books etc)? Are we able to hire a skip like in the UK? Are there organisations that deal with house clearances? Can we use the local 'dump' or is this just for residents? The property is just outside Villefranche Sur Mer.

Any advice would be gratefully received.
