Plastering a room: quote

Once the electricity is done, we’ll be able to plaster the room. I managed to get a plasterer in today Friday. He ball point quote for £400 to £500, to:
– plaster 4 walls
– plaster ceiling
– insulate outside wall (which has huge window)
– fix corner to ceiling on the right of the window

He will send detailled quote later. Let’s see. It could be it.

Electrician coming on Monday.
