Try a company called 'Red Jacks' who specialise in all kinds of small household jobs - They have a website. They are a mobile force who arrive by moped and charge a flat rate - It used to be £30 for the first hour and less thereafter - don't know what they charge now. A guy called 'Paddy' is particularly efficient but the others are fine too. They seem to be mainly Antipodeans. If you need a floor sanded, you would have to hire a sander independently for them to use since they only bring what they can carry on the bike.
Good luck! Beverly.
