Chandelier cleaning

Hi there,

I am working on a property in the London area and have a long chandelier around 4 metres in drop that needs professionally cleaning. 

It can be accessed from the landings it falls between, so while it could be dismantled it would no doubt be easier to clean in situ. I attach a photo and video for reference.

Please let me know if this is a job you would be interested in doing, and if so a rough price and timeframe.

Many thanks
