Garage full of furniture some vintage (Woodside Park N20)

Hi, we were due to have a load of furniture collected for charity from my aunt’s garage in whetstone and they’ve cancelled. We have to get it out tomorrow and some of it is vintage and of reasonable value also sentimentally so can’t go to landfill which is where it’ll be headed on Saturday. Has anyone got any suggestions of someone who might take the furniture tomorrow to sell it on and take the value of the furniture as payment (and maybe a bit of extra rubbish?) just trying to work out a way. Thanks
