Ok not quite gardening but garden related...
I have a large 3m diameter dining table and 7 chairs (folding teak, with slatted base and back so that means it will take longer than if they were solid) which need sanding and retreating with teak oil.
I'm going to get a chap I know who does odd jobs in to do it. How long would be reasonable to do this job or how much (we're in London if that's relevant!)
