Im a plasterer too, I put up a 12ft by 12ft ceiling this morning... by 11 oclock it was up and thats on my own with no poles or added help and set (skimmed) by 2 oclock!!
If I charged that sort of money i would be rich!!
Get the ceiling up yourself, youl need 9 boards for 12 by 12 and 2 multifinish and a role of scrim and drywall screws, materials today came to 60 quid for the lot!!
I know its a insurance job but fuck... £1150!! Im not charging enough!!
