Plastering job, what should I be paying roughly?

[kitessurfer]

Hi,
Continuing with my garage converison in Kent, I plan to carry out prep work on the walls i.e. plasterboard on walls, ceiling, jointing.
What would I expect to pay please to plaster these walls;
4 walls in total = 2 off 3x2mtr and 1 off 2x2mtr and 1 off 2x1mtr
Ceiling 4 x 2mtr.
If you're wondering why this doesn't measure up to garage size is because part of garage is set aside for wc/shower room which I will be doing myself.
thanks
KS

about £400 wether you board it or not.

1½ days work (but you’ll pay for 2!); so around £350 but no more than £400!
