The best way to do it is to 'terrace' it. I'd suggest that you get a gardner in to do it for you as it involves a considerable amount of manual work in creating the terraces. In this way you end up with a series of level beds at various heights (deopending on the height of the slope) which you can fill with plants. Maybe best to get a landscape gardner in to advise and quote.
If you don't take this approach you'll be limited in the type of plants which can be grown on sandy soil, together with a somewhat intemperate climate !
Sorry to be a killjoy !
