House clearance and storage

Hi all
We have made the sad decision to sell after not being able to visit our home for over a year and looking slim for this year. It isn’t full of stuff but we have sentimental things and some household/clothing that we’d like to get back somehow, some stuff for charity and who knows about furniture depending on buyers. Most of our friends from Portugal are now also here in the Uk so we don’t have anyone who can visit and pack up for us. Does anyone know if there are any trustworthy businesses that do this sort of packing/sorting according to instructions. Bit awkward having someone sort through your smalls! 😂. Only alternatives I can think of is to keep absolutely everything and get it into storage.

All ideas appreciated.
Thanks
