If it were my place, I would take the following into account, but berate me as required.
If the painting is getting done this week, has anyone got a five  or preferably 6 step ladder that could be dropped round. The prep work and painting of the picture rail in the lounge (at least) will require the use of one or a human pyramid!
Anyone got a spare mop or brush, as they are often ideal to use as a roller extension for ceilings and emulsion above the picture rail?
I'm OK at painting, but a bit out of practice, but if anyone wants to jump in feel free. If the prep work is done, will come down half a day to do undercoat and half a day for glossing (don't do mornings and if I do it's for my clients), so get the sandpaper out and get a key on the woodwork 
@Russian Evertonian !
Not sure how many brush sets and rollers are there so do you need to bring your own?
Anyone got any dust sheets to cover the furniture that can't be easily moved? (Flaming sofas)
Speaking of the sofas, 
@Frodsham Blue how easy (or difficult) is it to move the sofas from one room to another?
Reason being, if carpets being fitted by a pro will probably want a clear room.
