Job description

Please could I get a rough quote for decorating 2 bedrooms, both of which are about 12x12ft. The ceilings have been newly plastered and so need 50/50 first. They are low so easily accessible. The walls are sloped as are in eaves. I want to use water based paint in an f&b copy (I can supply or you get trade if cheaper). I'm based in Stow-cum-quy and need it doing yesterday!! Many thanks
