Interior painting of house lounge/dining/small kitchen/main bedroom

We would like our open plan living area (kitchen/lounge/dining) painted, main bedroom and +/- hallway. We have a lot of windows/bay window/doors so the surface area to paint isn't as large as the room looks (see pictures, sorry no hallway pictures) and we also don't think we need the ceiling painted as it is white and we want the walls painted white or off white. We are happy to supply paint depending on cost difference (please quote). Instead of painting 1 wall in the lounge we would like a quote for wallpaper to be put up on a 4 meter long wall in the living room! Can you advise how long this would take and when it can be done? The main areas we want painted firs is the open plan and main bedroom. October 10th vs September 13th is the date we move in. We maybe able to have the house empty if it is easier to do? May we also have the full 3 bedroom 2 bathroom (140m2) quoted as if not much difference will get the whole house painted or at least we will in the near future.
