Is this a paid job? Are you sure you are the right man to do it?
Have a look on the pages of this site all the info is there to read

What type of sandstone flags are they? Sandstone is generally not laid on a screed. Even though most sandstone is now calibrated, the thickness is not reliable enough to go on a screed. It would help to know the exactly what the stone is

Are you sure that's just not bad wording, they probably mean on a 50mm bedding course, but their calling it screed because it's sharp sand/cement?
