Plaster a small room ceiling and four walls

I need aprox 10 plasteeboards plastered in dover ready for painting on stud walls in a flat plaster is provided and will be oayed in cash on the friday of compleation if not earlyer

We need a window drip installed in the external render above the front facing upper bedroom window. Window can be accessed by ladder or self-build scaffold tower. This is to resolve a consistent leak where in heavy rain, water drips on the inside of the window. No other way the water is getting in (roof is fine, wall painted, window resealed etc). We're in East Folkestone. Thanks
