how much roughly would in cost to pay a decorater to paint a 12x15ft lounge?...

...will take two coats including? ceilings skirtings etc?

3 days at 150 quid/day I would have thought; unless there is a lot of prep to do...

Three to five hundred for a painter, not a decorator. Otherwise, anything fancy will cost more. Use primer as a base coat.
